John Van Antwerp MacMurray (1881–1960) was an American attorney, author and diplomat best known as one of the leading China experts in the U.S. government. He served as Assistant Secretary of State from November 1924 to May 1925, and was subsequently appointed Minister to China in 1925. Although MacMurray had coveted the China post, he soon fell into disagreement with the State Department over U.S. policy towards the ruling Kuomintang government. He resigned the position in 1929 and briefly left the foreign service. Following several years in academia, MacMurray returned to the State Department to become Minister to Estonia, Latvia and Lithuania from 1933 to 1936. He later served as ambassador to Turkey from 1936 to 1941, and then was made a special assistant to the Secretary of State unti
