Stone attended
Columbia Law School from 1895 to 1898, received an
LL.B., and was admitted to the New York bar in 1898. Stone practiced law in
New York City, initially as a member of the firm Wilmer and Canfield, which (near the time of William Nivison Wilmer's death in 1907) was renamed Satterlee, Canfield & Stone. Stone's partners there were
Herbert Livingston Satterlee (who became Assistant Secretary of the Navy) and George Folger Canfield (an early professor at Columbia Law School). Later, Stone became a partner in what is now a
white-shoe law firm,
Sullivan & Cromwell. He taught at Columbia Law School as a lecturer (1899–1902) and professor (1902–1905), beginning at a modest salary of $2,000 that eventually increased to $3,000. He served as the school's dean from 1910 to 1923. Nevertheless, he recognized the courage required to persist as a conscientious objector: "The Army was not a bed of roses for the conscientious objector; and the normal man who was not supported in his stand by profound moral conviction might well have chosen active duty at the front as the easier lot."
After the war At the end of the war, he criticized Attorney General
A. Mitchell Palmer for his attempts to
deport aliens based on administrative action without allowing for any judicial review of their cases. During this time Stone also defended free speech claims for professors and socialists. Columbia soon became a center of a new school of jurisprudence,
legal realism. In 1923, disgusted by his conflict with Butler and bored with "all the petty details of law school administration" that he dubbed "administrivia", Stone resigned the deanship and joined the prestigious
Wall Street firm of
Sullivan & Cromwell. He received a much higher salary and headed the firm's litigation department, which had a large corporation and estate practice (including
J.P. Morgan Jr.'s interests).
Attorney general On April 1, 1924, he was appointed
United States Attorney General by his Amherst classmate
President Calvin Coolidge, who felt Stone would be perceived by the public as beyond reproach to oversee investigations into various scandals arising under the
Harding administration. which later became the
Federal Bureau of Investigation (FBI), and directed him to remodel the agency so it would resemble Britain's
Scotland Yard and become far more efficient than any other police organization in the country. A pro‑active Attorney General, Stone argued many of his department's cases in the federal courts and launched an anti‑trust investigation of the
Aluminum Company of America, controlled by the family of fellow cabinet member
Andrew Mellon, Coolidge's Secretary of the Treasury. In the 1924 presidential election, Stone campaigned for Coolidge's re‑election. He especially opposed the left-wing Progressive Party's candidate,
Robert M. La Follette, who had proposed that Congress be empowered to reenact any legislation that had been struck down by the Supreme Court. Stone found this idea threatening to the integrity of the judiciary as well as the separation of powers. ==U.S. Supreme Court==
