John William Cousin (1849–1910) was a British writer, editor, and biographer who made significant contributions to the field of literary reference. Born in Scotland to William and Anne Ross Cousin—his mother being a well-known hymn-writer—Cousin pursued a career that bridged the worlds of finance and literature. He was a fellow of the Faculty of Actuaries and served as the secretary of the Actuarial Society of Edinburgh, demonstrating a diverse range of professional talents.\n\nDespite his actuarial background, Cousin is remembered primarily for his literary endeavors. In 1907, he revised and wrote the introduction for an edition of Henry Wadsworth Longfellow's epic poem Evangeline. However, his enduring legacy rests on his work as an editor and compiler of literary history.\n\nCousin's most notable achievement was A Short Biographical Dictionary of English Literature, published in 1910 as part of J.M. Dent's prestigious "Everyman's Library" series. This comprehensive collection of biographical entries on numerous authors and literary figures became a staple reference work. Long after his death, the bulk of Cousin's research and writing was utilized by David Clayton Browning to compile the Everyman's Dictionary of Literary Biography in 1958, which was reprinted extensively throughout the 1960s and 1970s.
