Karl Compton

Karl Taylor Compton was born on September 14, 1887, in Wooster, Ohio, the eldest child of Elias and Otelia (Augspurger) Compton. He grew up on and around the campus of the College of Wooster, where his father taught Latin, philosophy, and psychology before serving as the college's first dean. Elias had originally intended to become a missionary but went into teaching after graduate study in theology and psychology; he earned a doctorate from Clark University in 1889. His mother's family were Mennonite farmers of German origin who had settled in Ohio, and the household combined Presbyterian observance with an unusual intellectual openness. Karl's siblings—Mary (b. 1889), Wilson (b. 1890), and Arthur (b. 1892)—grew up in the same environment and all made careers in scholarship or public life. Beginning in 1897, the family spent summers camping at Otsego Lake in Michigan, where Karl developed a lasting taste for fishing, canoeing, hiking, and hunting that stayed with him for life. The Compton children were shaped by Elias's wide-ranging curiosity. Alongside Homer and Walter Scott, the children read popular science writing about electricity and astronomy; Elias was one of a small minority of Wooster faculty who publicly defended evolutionary theory. At Wooster, Karl moved from a brief interest in biology to physics, where he served as a laboratory assistant to George Bacon and excelled in mathematics. He was also a competitive athlete—captain of the football team in his senior year—and was remembered for an inventive freshman prank involving the college heating plant's 150-foot smokestack that displayed his class numerals for weeks. From the age of eleven he took paid work to cover college expenses: carrying hods on construction projects, skinning mules, canvassing books, working on farms and in tile and brick factories, and surveying what he later recalled as the first mile of state-paved road in Ohio. He graduated cum laude with a bachelor of philosophy degree in 1908 and completed a master's degree under Bacon the following year. His master's thesis, on the principle of the Wehnelt electrolytic interrupter, was published in the February 1910 issue of Physical Review. A job offer from a missionary college in Korea, which he had half expected to accept, materialized at the same moment; his father persuaded him to pursue a doctorate at a research university instead. Browsing university catalogs, he was drawn to Princeton by the presence of two Cavendish-trained physicists, James Jeans and Owen Richardson, and enrolled there in 1910. Richardson—a legendarily poor lecturer—proved a difficult mentor, but Compton adapted. He focused his doctoral research on the photoelectric emission of electrons, contributing experimental evidence for Richardson's law of thermionic emission. Working with Richardson, he published several papers on the photoelectric effect and electron theory. Their joint 1912 paper in Science was among the earliest experimental confirmations of Einstein's 1905 explanation of photoelectric emission. In 1912 Compton received the Ph.D. summa cum laude, a distinction Princeton rarely awarded. He was also awarded the Porter Ogden Jacobus Fellowship. He then completed a postdoctoral year at Princeton before taking up his first teaching position. == Teaching career ==

In June 1913, Compton married his Wooster classmate Rowena Rayman and the couple traveled to Portland, Oregon, where he had accepted an instructorship in physics at the newly founded Reed College. He took sole charge of physics instruction and laboratory development, but the salary was too low to sustain a family once their daughter Mary Evelyn was born in December 1914. Richardson recommended him for a position at Yale. Princeton moved first, offering an assistant professorship, and Compton returned there in 1915. At Princeton, his teaching acquired a reputation that his supervisor's had not. Richardson's lectures on electron theory were, by his own students' account, among the worst given in the field. Compton's "clear, goal-oriented" instruction became a cornerstone of Princeton's physics program. He declined an offer from Willis Whitney, director of research at General Electric, but agreed to serve as an outside consultant, an arrangement that would last more than a decade. He and his brother Arthur co-invented the Compton electrometer, a sensitive voltage-measuring device, during this period. During the First World War, Compton contributed to the Allied scientific effort in several capacities. In the summer of 1917 he joined physicist Augustus Trowbridge at Princeton in studying sound ranging methods for locating enemy artillery, and was subsequently attached to Edison Laboratories for research on torpedo propulsion and submarine detection. From December 1917 through January 1919, working through Robert Millikan and the National Research Council, he served with the U.S. Signal Corps in Washington, D.C., and then in Paris as associate scientific attaché at the U.S. embassy, where he prepared reports on artillery-sound and submarine-detection techniques for military and naval intelligence. Rowena died suddenly in October 1919 of peritonitis from a ruptured appendix, while expecting a second child. Compton remarried in July 1921. His second wife, Margaret Hutchinson, was the sister-in-law of a Princeton classics professor who had helped Compton through the period following Rowena's death. Margaret's father taught classics and mathematics at the University of Minnesota, and she was herself a Minnesota graduate who had gone into YWCA field work. The newlyweds honeymooned by canoe on the Boundary Waters Wilderness in northern Minnesota, covering two or three hundred miles over three weeks. They had two children: Jean Corrin (b. 1924) and Charles Arthur (b. 1927). Returning to Princeton after the Armistice, Compton concentrated his research on electron collisions and became a pioneer in the experimental study of electrical plasmas, aggregates of subatomic particles whose behavior would later prove significant for controlled nuclear fusion. Over the following decade, his laboratory produced over one hundred papers on thermionic effects, ultraviolet spectroscopy, and the behavior of electrons in gases. He was made a full professor in June 1919. His standing in the discipline rose steadily through professional society leadership. He served as vice president of the American Physical Society in 1925 and president in 1927, chaired the physics section of the National Academy of Sciences from 1927 to 1930, and was elected a fellow of the Optical Society of America and a member of the American Philosophical Society (1923) and the National Academy of Sciences (1924). In 1926, a sabbatical year at the University of Göttingen placed him among a cohort of American physicists working under Max Born and James Franck; it was there that he met a young American graduate student, J. Robert Oppenheimer. The University of Chicago recruited him heavily across this period, at one point drawing a signed contract. In 1924 it proposed to hire the brothers Karl and Arthur together; Arthur's work on X-ray scattering was then gaining the momentum that would earn him the Nobel Prize in 1927. Princeton countered with elevated salaries, research funds, and a new endowed chair, the Cyrus Fogg Brackett professorship, freeing Compton from undergraduate teaching to focus on graduate work and research. In 1929 he became head of the physics department, intent on building Princeton's program into the finest in the country. The MIT Corporation's search for a new president intersected this plan the following January. Gerard Swope, a GE executive and MIT Corporation member who had long known Compton as a consultant, asked him in a private meeting whether he would consider the post. Compton was reluctant: he had no administrative ambitions, no taste for fundraising, and a laboratory and graduate program at a satisfying peak. He was persuaded by a conversation with Frank Jewett, president of Bell Labs, who explained that what industry needed from MIT was not practical technicians but graduates broadly educated in science and mathematics; personnel capable of recognizing and exploiting new technological opportunities. "Jewett, who really knows these engineers, tells me I'm what the Institute needs," Compton told his wife Margaret on the drive home from Princeton Junction. == MIT presidency before World War II ==

Compton was inaugurated on June 6, 1930, before several thousand guests assembled in MIT's Great Court. The Great Depression created significant new headwinds for the Corporation's ambitious plans for science investments. The same month, Gerard Swope announced the Technology Loan Plan, a plan to raise tuition and provide loan-based financial assistance to students in need, drawing contributions from George Eastman, Alfred P. Sloan Jr., and several members of the du Pont family. Academic reforms Compton's first sustained effort was in the science departments. He recruited John C. Slater, a theoretical physicist who had been an associate professor at Harvard, to chair the physics department, and brought George Harrison from Stanford to lead experimental work. Slater reorganized the graduate program and helped recruit a new generation of theoreticians and experimentalists; when six National Research Council fellows chose to spend time at MIT in 1932–33, the department's changed reputation was evident. The opening of the George Eastman Research Laboratories in 1932, which Compton had helped design to minimize vibration and foster contact between faculty and students, gave physics and chemistry a shared home for this work. Compton's first encounter with Vannevar Bush was a confrontation. In 1931, Compton imposed a one-day-a-week limit on outside consulting and required faculty to deposit half their consulting income into a Professors' Fund intended to raise salaries and discourage work unrelated to the Institute's mission. Bush, whose own consulting arrangements predated the policy, charged into the president's office and announced he was leaving MIT. Compton offered an exemption; Bush refused it. "Your whole damn fool plan," he said, "will dissolve in a welter of exceptions." Bush did not leave MIT. He found Compton's willingness to hear him out disarming, and Compton recognized in Bush exactly the blunt, operationally minded partner he needed. After the October 1931 death of his predecessor, Samuel Stratton, Compton revived the dormant vice presidency. Bush suggested himself for the job. Compton, seeing their opposite temperaments as complementary, agreed, and the executive committee approved Bush as vice president and dean of engineering in May 1932. One colleague described the partnership as a balance of contrasts: Compton was diplomatic and inclined to give everyone the benefit of the doubt, while Bush brought shrewd tactical judgment and did not mind making enemies. Together they divided responsibilities, with Compton overseeing the science departments, foundations, and government relations, and Bush running the engineering school and handling patent matters. At the same time, Compton moved quickly to reorganize the Institute's administration. He proposed grouping MIT's departments into three degree-granting schools: Engineering, Science, and Architecture, alongside a Division of Industrial Cooperation and a Humanities division. A Graduate School dean would oversee admissions and degree requirements without direct curricular authority. An administrative council of the president, vice president, deans, and directors would meet weekly. The intent, as Compton framed it, was to bring science and architecture into parity with engineering, helping define "a fine university...in which a great engineering school is one important part, but not the whole." Compton sought to expand MIT's research funding beyond industrial contracts. He persuaded the Rockefeller Foundation, in a significant departure from its standard policy, to provide MIT a general research fund of $170,000; total annual foundation support nearly tripled from $37,000 in fiscal year 1936 to $111,000 by 1939. In engineering, he appointed research-oriented faculty to department chairs, and in 1938 recommended to Swope the elimination of Mining Engineering, Electrochemical Engineering, and Sanitary Engineering as programs he considered obsolete. Industry relationships Compton and Bush moved to centralize MIT's relationship with industry. The Division of Industrial Cooperation and Research, which had coordinated industrially sponsored work since 1920, was renamed the Division of Industrial Cooperation in 1932 and placed under presidential authority. Where department heads had previously negotiated contracts with sponsors and notified the administration only afterward, every research agreement now required approval at the top. Compton and Bush also established MIT as one of the first major universities to engage in patent licensing. The Corporation endorsed a formal patent policy in 1932, over the objections of industrial members who considered it improper for an educational institution to hold patents. A patent committee was created in 1933, and in 1937 an agreement with the Research Corporation transferred patent administration to an outside body, shielding MIT from accusations of competing with industry. Swope himself had opposed the patent policy, a sign that Compton was willing to act against the interests of those who had helped recruit him. When General Electric sought exclusive licensing rights to Robert Van de Graaff's high-voltage generator as a condition of further collaboration, Compton refused outright. The Professors' Fund was abandoned within a few years, undone by faculty opposition, but Compton regarded it as having established the principle that the faculty's first obligation was to the Institute. Separately, in the fall of 1932, as the Depression deepened, Compton announced a salary reserve plan withholding 10 percent of each professor's salary above $500 and depositing it into an emergency pool. When conditions improved the withheld funds were returned intact. By the mid-1930s, the results of Compton's reforms were visible enough that MIT was invited to join the Association of American Universities, whose membership represented the leading research universities in the country. Graduate enrollment grew substantially, a school of science was consolidated, and the ratio of research to teaching activity shifted in favor of the former. On the eve of the Second World War, however, the transformation remained incomplete. Roughly 80 percent of MIT students were still enrolled in the engineering school, and the close relationship with industry persisted. Compton and Bush had laid the institutional foundations for a science-based technological university, but the full realization of that vision awaited federal patronage on a scale that the Depression had made impossible. Advocacy for science funding The Depression thrust Compton into a new public role. As industries shed workers and the Technocracy movement blamed scientific progress for unemployment, he mounted a counterargument: that science, rather than displacing labor, generated new industries and new employment. In a 1933 essay rebutting the Technocrats, he argued that if civilization were destroyed, the fault would lie in human stubbornness rather than in the machines humans had made. Writing in the New York Times Magazine in December 1934, he put the argument in terms that would circulate for years: new industries, he wrote, were "like babies — they need shelter and nourishment, which they take in the form of patent protection, financing, and the chance of reasonable profits. But, before all, they need to be born, and their parents are science and invention." Throughout the mid-1930s he maintained an output of public addresses and essays in Vital Speeches of the Day, The Atlantic, and Science, consistently framing research expenditure as investment rather than a luxury in times of austerity. Compton also worked to organize American science for advocacy. In 1931, he helped found the American Institute of Physics and served as chairman of its governing board until 1936. The AIP originated as an attempt to reduce publishing costs by centralizing the editorial operations of several physics societies. It became quickly became "a trade association in defense of science and all its works," bringing the separate societies into a federation that spoke collectively for the discipline. In July 1933, President Roosevelt created the Science Advisory Board by executive order, on the initiative of the geographer Isaiah Bowman and with the backing of Agriculture Secretary Henry Wallace. Roosevelt appointed Compton chairman. The Board received no federal funds even for its own operating expenses and was given a two-year life, but Compton set to work on a substantive program. By December 1934 he had brought the Board to endorse a proposal to the President: $75 million over five years for research, primarily in universities, and a permanent scientific advisory body to assist the Bureau of the Budget in reviewing the programs of government technical agencies. The proposal insisted that the distribution of funds be insulated from political interference; only the scientific merit of projects should govern the allocations. This placed Compton in conflict with New Deal planners who wanted any research program tied to the social sciences and, ultimately, to immediate relief work. Harold Ickes forwarded the proposal to the National Resources Board, whose members—Wesley Mitchell, Charles Merriam, and Roosevelt's uncle Frederick Delano—regarded the country's problems as social and economic before they were technological, and found Compton's scale of request "staggering." When Roosevelt conditioned any science appropriation on ninety percent of the spending going to workers drawn from relief rolls, the program was effectively blocked. The Board went out of business on schedule in 1935. Compton, by his own account, felt like a man who had bet on the wrong horse. The proposal itself was not forgotten: Compton's plan for a government science fund, administered by scientists and insulated from political control of programmatic purpose, reappeared virtually intact a decade later in Vannevar Bush's Science, The Endless Frontier, the report widely credited as the founding document of the National Science Foundation. New England and venture capital With federal advocacy stymied, Compton turned after 1936 to a regional strategy. New England's textile industry was in structural decline, and within the New England Council there was growing recognition that the universities and research laboratories concentrated around Boston represented an asset few other regions could match. In 1939, at Compton's suggestion, the Council formed a New Products Committee to examine how science might compensate for the region's manufacturing losses. The committee brought together Compton, the Harvard Business School professor Georges Doriot, the Vermont manufacturer Ralph Flanders, and the investment trust president Merrill Griswold. Its November 1940 annual meeting concluded that while capital for new ventures existed, what was lacking was the organizational capacity to evaluate technical opportunities rigorously enough to give investors reasonable assurance. The that pointed toward the kind of institution, a professional venture capital fund, that Compton and his colleagues would build after the war. A parallel experiment, Enterprise Associates, took a more direct approach, pooling $300,000 from private stockholders to finance promising research projects. Compton and Griswold participated. When Germany's invasion of France in May 1940 prompted most participants to withdraw from the group's first commitment, the episode exposed a structural problem: an organization with only enough money to locate and study opportunities, then pass the hat for backing, was hostage to events outside its control. Compton and Griswold concluded that any workable venture firm would need its own capital, committed in advance. The war interrupted these efforts before they could be resolved, but the core network was assembled; Compton would reconvene it in 1946. Health Although he appeared robust, Compton's commitments strained him. He had arrived at MIT in 1930 nursing a stomach ulcer, managed by an easygoing disposition and a regimen of midmorning milk. In 1936, after the peak stress of the Depression-era reforms and the Science Advisory Board struggle, he suffered what appeared to be a mild stroke. His doctors traced the episodes to arterial hardening worsened by cigar smoking, a habit he had acquired in Paris during the First World War. Friends grew accustomed to watching him swear off cigars and then resume. In the fall of 1937, Vannevar Bush proposed a remedy: both men should find country retreats where they could spend weekends away from Cambridge. Bush drew a circle on a map around Boston, calculated distances and prices, and turned up a house near Jaffrey Center, New Hampshire. Compton bought it within two weeks, and the family used it as a weekend escape through the war years. ==World War II==

MIT and the Radiation Laboratory When Vannevar Bush organized the National Defense Research Committee (NDRC) in June 1940 to mobilize university scientists for defense research, Compton was among its founding members, heading Division D, which covered instruments, controls, and radar. That September, a British technical delegation led by Sir Henry Tizard arrived in the United States carrying a resonant-cavity magnetron. The compact device that could generate microwave pulses at powers roughly a thousand times greater than American equivalents, making high-resolution radar practical for the first time. Loomis, Compton, and Bush were unanimous that a dedicated civilian laboratory should be built around it. When two prospective sites fell through, Bush turned to Compton with the request that MIT accommodate the work. Compton agreed, and the MIT Radiation Laboratory was organized on the MIT campus in late 1940, with Lee DuBridge recruited from the University of Rochester to direct it. The original NDRC contract, for $455,000, was the first large wartime research contract placed with an American university. The Radiation Laboratory's survival was not assured. When the lab's early airborne intercept prototype failed to meet Army specifications in spring 1941 and its future looked uncertain, Compton quietly secured an anonymous commitment from John D. Rockefeller Jr. to cover technical staff salaries through June 1942, keeping the enterprise afloat. The laboratory grew rapidly thereafter. By 1944 it employed nearly 4,000 physicists, engineers, and technicians; by the war's end it had developed 150 distinct radar systems. Over the same period MIT received nearly 400 war research contracts worth $93 million, and federal funding to the Institute rose from $42,000 in fiscal year 1940 to nearly $38 million in 1944. MIT also ran a radar school that trained nearly 8,900 officers, enlisted men, and civilians. DuBridge later wrote that Compton's leadership had been a "vital factor" in the Laboratory's operation and success. When the NDRC was absorbed into the newly created Office of Scientific Research and Development (OSRD) in 1941, Compton continued as both an OSRD member and chairman of a radar research and development subcommittee under the Joint Committee on New Weapons and Equipment. In August 1942, Roosevelt appointed him to the Rubber Survey Committee alongside Bernard Baruch and James Conant, which investigated technical disputes in the development of synthetic rubber following the loss of supply routes through Southeast Asia. The UK radar mission of the Telecommunications Research Establishment In late April 1943, Compton led the United States Special Mission on Radar to Britain, with DuBridge traveling at his side. Over the following month the mission visited British radar research establishments and operational commands, including the Telecommunications Research Establishment. The two allies agreed that the United States should generally take the lead on longer-range development projects, such as one-centimeter radar, while each country continued to develop overall systems independently. The mission returned with a package of radar policy proposals that shaped the Rad Lab's agenda for the remainder of the war, including the acceleration of H2X bombing radar for the Eighth Air Force. The following year Compton chaired the committee that received a reciprocal British radar mission to the United States. Office of Field Service and the Pacific In October 1943, Bush established the Office of Field Service (OFS) within OSRD to deploy civilian scientists directly to combat theaters, and appointed Compton as its chief. The OFS filled a gap that wartime communications could not bridge: field commanders needed scientists present in forward areas to diagnose failures in new equipment, train troops in its use, and transmit operational problems back to laboratories at home. Compton's first major assignment as OFS chief was a reconnaissance mission to the Pacific in December 1943. Traveling as an expert consultant to the Secretary of War—identified in his papers as equivalent in treatment to an Army colonel if captured—he conferred with Admiral Chester Nimitz, General Douglas MacArthur, and the senior commanders of all three major Pacific theaters over the course of thirty-two days. At the end of January 1944 he presented MacArthur with a summary of the scientific assistance OSRD could provide. MacArthur approved it immediately, saying it exceeded his expectations. Compton returned to Boston with notebooks full of requests and began assembling teams of specialists. Compton arrived in Manila on August 5, 1945, bearing the assimilated rank of Major General, to organize and head the OSRD Pacific Branch—the day before the first bomb fell on Hiroshima. The branch had been resourced for laboratory space, 300 tons of equipment, and some 200 scientists. Japan accepted the Potsdam terms on August 14, dissolving in days the invasion he had been preparing to support. Compton and Edward L. Moreland were then asked to lead a scientific intelligence mission into Tokyo, entering the city among the first Americans to do so since the war began. Their team—drawn partly from Radiation Laboratory staff and using alumni lists of MIT, Caltech, Harvard, Chicago, and Berkeley to locate Japanese contacts—interviewed military officers and scientists on Japan's atomic and radar programs. Compton found that Japanese physicists had miscalculated the feasibility of a bomb and redirected their atomic effort toward power generation; the laboratory apparatus built for that purpose had been destroyed in a bombing raid before any tests were made. Japan's radar program lagged approximately three years behind American practice in conception and further still in production. Before leaving, Compton negotiated an agreement that Japanese cyclotrons would be preserved for medical research rather than destroyed. On returning home, he learned the War Department had dumped them into the ocean. Compton wrote Secretary of War Robert Patterson a letter condemning what he called an act of "utter stupidity." The Interim Committee and the atomic bomb In spring 1945, Secretary of War Henry Stimson assembled the Interim Committee to advise President Harry Truman on the use of the atomic bomb. Compton served as one of its scientific members alongside Bush and Harvard president James Conant. At the advisory level closest to Stimson, the three had joined in recommending that the bomb be used without warning against a military target in a populated area—a position that differed from the Franck Report, signed by Manhattan Project scientists in Chicago, which urged a prior demonstration. These observations, combined with what he had learned in Tokyo, underpinned an article Compton published in the December 1946 Atlantic Monthly, "If the Atomic Bomb Had Not Been Used." Compton wrote the piece at the urging of Harvard president James B. Conant, who was seeking prominent voices to publicly defend the bombing decision. Drawing on his interviews with Japanese officers and his knowledge of the invasion planning, Compton argued that the bomb had strengthened the position of peace advocates within the Japanese government and precipitated a surrender that conventional operations alone could not have forced. When Compton sent Truman the published article, the president replied in a letter dated December 16 calling it "the first sensible statement I have seen on the subject." The Atlantic published a portion of Truman's letter in its February 1947 issue. == Post-presidency ==

at the 1949 MIT Midcentury Convocation Compton resigned the MIT presidency in October 1948 and was immediately elected chairman of the MIT Corporation, a position he held until his death on June 22, 1954. His final years did not mark a withdrawal from public life. Beyond MIT, he served as a trustee of the Ford, Rockefeller, and Sloan Foundations, the Sloan-Kettering Institute, the Brookings Institution, and Princeton University. He remained an active participant in the ventures he had helped create, though a series of cardiovascular episodes forced a partial retreat in 1949. Organization of venture capital The wartime interruption had not weakened Compton's conviction that New England's economic recovery depended on channeling scientific research into new commercial enterprises, or his diagnosis that what was missing was a professionally managed pool of risk capital. Following Japan's surrender, Compton reconvened his colleagues from the New Products Committee. ARD was incorporated on June 6, 1946, with Ralph Flanders serving as its interim president until Georges Doriot could was discharged from military service. By December, ARD had raised $3.5 million from nine financial institutions, two insurance companies, and four university endowments: MIT, Rice Institute, the University of Pennsylvania, and the University of Rochester. Individual investors supplied the remainder. Compton's idea became an industry model: ARD was the first venture firm to draw on institutional capital rather than family wealth. Compton served on ARD's three-member MIT technical advisory board alongside chemical engineering professor Edwin Gilliland and aeronautics department head Jerome Hunsaker, and joined the board of Tracerlab, one of ARD's first technology investments. Tracerlab, founded by MIT graduates to sell radioactive isotopes and manufacture radiation detection equipment, had been near bankruptcy before ARD provided $150,000 on terms that commercial lenders had refused. The other startup investment, High Voltage Engineering Corporation, was launched by MIT scientists Robert Van de Graaff and John Trump in a converted Cambridge parking garage. Articulating the founders' hope of using compact particle accelerators for cancer therapy, Compton urged Doriot to back High Voltage Engineering despite its uncertain commercial prospects, arguing that the humanitarian value of cancer treatment with X-rays justified the risky investment. Doriot provided $150,000. On Compton's death in 1954, Doriot wrote to ARD stockholders that his foresight and vision were responsible in great part for the formation of the corporation, and that Tracerlab and High Voltage in particular would miss his counsel. Universal military training On December 19, 1946, President Truman named the members of a new President's Advisory Commission on Universal Training and appointed Compton its chairman. The commission was charged with studying whether the United States should adopt peacetime conscription. Compton brought unusual preparation to the role: his wartime service had spanned the NDRC, the OSRD, the Interim Committee, and the Pacific theater, and he had come to believe that a trained reserve was the indispensable complement to the technological superiority he had spent his career building. The commission completed its work in five months. Its report, A Program for National Security, was submitted to Truman on May 29, 1947, and recommended universal training by unanimous conviction. Congress held hearings the following year and declined to act, enacting instead a renewed selective service law that deferred military training entirely. Killian later wrote that Compton's disappointment was deep, and that the congressional rejection foreshadowed a growing unwillingness among Americans to sustain the commitments that postwar security required. When Congress created the National Security Training Commission in 1951, Truman nominated Compton as one of its civilian members. The commission produced further reports in 1951 and 1952; none resulted in enacted legislation during Compton's lifetime. Research and Development Board When Vannevar Bush stepped down as chairman of the Research and Development Board of the National Military Establishment in 1948, he was determined that his successor have sufficient standing to make the board function. His recommendation was Compton. The National Security Act of 1947 established the board to coordinate research across the Army, Navy, and Air Force under a civilian chairman, a peacetime successor to OSRD intended to preserve a civilian voice in defense policy. Truman appointed Compton in October 1948, the same month Compton relinquished the MIT presidency. The assignment proved punishing. The newly unified Department of Defense was beset by interservice rivalries and budget conflicts, and Compton found himself trying to build a coordinating structure across services that resisted civilian direction. He developed severe headaches—briefly and incorrectly diagnosed as a brain tumor—and was hospitalized with chest pains. In August 1949, a stroke at a Washington luncheon temporarily paralyzed his throat. On November 2 he wrote his resignation to Truman and returned to Cambridge. == Death and legacy ==

Compton suffered a heart attack in New York in June 1954 while attending a meeting; six days later, on June 22, a blood clot ended his life. He was survived by three children from two marriages and several grandchildren. At a memorial service held in MIT's Great Court, the Reverend Theodore Ferris described him as a man "with one eye continually and honestly on the facts and the other on the stars." graduation with Truman and General Omar Bradley Compton's most lasting achievement was the transformation of MIT from an engineering school into a research university strong in basic science, a process he set in motion in 1930 and that his wartime and postwar successors built upon. During his presidency, the educational model he developed—coupling fundamental research with advanced graduate training and encouraging faculty to bring discoveries into commercial use—was widely imitated. His advocacy for federal support of university research, pursued through the Science Advisory Board, the NDRC, and his many public addresses, helped establish the framework of government-university partnership that became characteristic of postwar American science. Over his career he received thirty-two honorary degrees and numerous awards, among them the Presidential Medal for Merit (1946), the Public Welfare Medal of the National Academy of Sciences (1947), the Hoover Medal (1950), and honorary commander of the Order of the British Empire. He was promoted to officer in the French Legion of Honor in 1951. The venture capital firm he co-founded, American Research and Development Corporation, provided $70,000 in seed funding to two MIT engineers in 1957 to start the Digital Equipment Corporation, an investment that eventually returned more than 70,000 percent and helped make the Route 128 corridor a center of the technology industry. The Compton lunar crater is named jointly for Karl and his brother Arthur. == Awards and honors ==

Compton published nearly 400 works between 1910 and 1954. His early career produced over one hundred papers in experimental physics, primarily on electron behavior in gases, photoelectricity, and spectroscopy. After becoming MIT president in 1930, his output shifted decisively toward science policy, engineering education, and public advocacy for research funding.
