Adams, James Truslow (1878-1949), a United States historian. Adams was an authority on the history of New England and the New England Adamses (to whom he was not related). He was awarded the Pulitzer Prize in history in 1922 for The Founding of New England (1921). His works include The Adams Family (1930) and The Epic of America (1931), an interpretive history of America since the Spanish explorations.

Adams was born in Brooklyn, New York. He graduated from Brooklyn Polytechnic Institute in 1898, and received an M.A. degree from Yale University in 1900. After 12 years as a successful banker and stockbroker, Adams retired in 1912 to study and write history. He was an army captain in World War I, and served on special duty at the Paris Peace Conference of 1919.

His other books include: Revolutionary New England, 1691-1776 (1923); New England in the Republic, 1776-1850 (1926); Provincial Society, 1690-1763 (1927); The March of Democracy (2 volumes, 1932-33); and Henry Adams (1933). Adams edited The Dictionary of American History (6 volumes, 1940); The Atlas of American History (1943); and Album of American History (4 volumes, 1944-48). (Both the Dictionary and the Album added volumes after his death.)
