Adam B. Ulam was born on April 8, 1922, in Lwów (then a major city in
Poland; now
Lviv in
Ukraine), to the parents of a wealthy well-assimilated Jewish family. After graduating from high school, on or around August 20, 1939, his 13-years-older brother
Stanisław Ulam, a famous mathematician and key contributor to the
Manhattan Project, took him to the
United States to continue his education. Their father had, at the last minute, changed their departure date from September 3 to August 20, most likely saving Adam's life since on September 1 the
Second World War began, with
Nazi Germany's invasion of Poland. Apart from the brothers Ulam, all other family members who remained in Poland were murdered in
the Holocaust. Adam had United States citizenship by 1939, and tried to enlist in the US army twice after the United States entered the war, but was rejected at first for having "relatives living in enemy territory" and later for myopia. He studied at
Brown University and taught briefly at
University of Wisconsin–Madison. After studies at
Harvard University (1944–1947), he got a doctoral degree under
William Yandell Elliott for his thesis
Idealism and the Development of English Socialism, which was awarded the 1947 Delancey K. Jay Prize. He became a faculty member at Harvard in 1947, he received tenure in 1954, and until his
retirement in 1992 was Gurney Professor of History and Political Science. He directed the Russian Research Center (1973–1974) and was a research associate for the Center for International Studies at the
Massachusetts Institute of Technology (1953–1955). He was a member of both the
American Academy of Arts and Sciences and the
American Philosophical Society. He married in 1963, divorced in 1991, and had two sons. On March 28, 2000, he died from
lung cancer in
Cambridge, Massachusetts, at the age of 77, and was buried at the
Mount Auburn Cemetery. ==Works==
