Trevelyan, the name of two British historians, father and son.

Sir George Otto Trevelyan

(1838–1928), the father, was both a historian and a statesman. He was noted especially for a definitive biography of his uncle, historian Thomas B. Macaulay, Life and Letters of Lord Macaulay (1876). His American Revolution (1909) also became a classic. Trevelyan graduated from Trinity College, Cambridge, in 1861. In 1865 he was elected to Parliament as a Liberal. Until he retired in 1897, he was almost constantly in public office, holding several minor cabinet posts.

His other books include Early History of Charles James Fox (1880); George III and Charles Fox (2 volumes, 1912–14).

George Macaulay Trevelyan

(1876–1962), the son, was one of the most eminent historians of his time. His belief that history should be written for the general reader as well as the scholar significantly influenced 20th-century historians. Trevelyan graduated from Trinity College, Cambridge. He served as professor of modern history at Cambridge, 1927–40, and as master of Trinity, 1940–51.

His best-known works include a three-volume study of Giuseppe Garibaldi (1907–11); History of England (1926); England Under Queen Anne (3 volumes, 1930–34); English Social History (1944).
