Arthur Christopher Benson (24 April 1862 - 17 June 1925) was an English essayist, poet, and author and the 28th Master of Magdalene College, Cambridge.
Benson was one of six children of Edward White Benson (Archbishop of Canterbury, 1882 - 96) and his lesbian wife Mary, sister of the philosopher Henry Sidgwick. The Benson family was exceptionally literate and accomplished, but their history was somewhat tragic. A son and daughter died young; and another daughter, as well as Arthur himself, suffered badly from a mental condition that was probably manic-depressive psychosis, which they had inherited from their father. None of the children ever married. Arthur was homosexual, though his diaries suggest he had few or no sexual relationships.
Despite his illness, Arthur was a distinguished academic and a most prolific author. He was educated at Eton and King's College, Cambridge. From 1885 to 1903 he taught at Eton, returning to Cambridge to lecture in English literature for Magdalene College. From 1915 to 1925, he was Master of Magdalene. From 1906, he was a governor of Gresham's School.
