After working as an attorney, Acheson moved into public service and held a series of senior posts in the State Department. In 1949 he became Secretary of State and remained in that post until 1953.

After leaving public office, Acheson returned to private life and to legal and financial work while remaining an active commentator on foreign affairs.
