Hilary Sumner-Boyd (1910–1976)

"Hilary Sumner-Boyd was also extremely influential in the development of the modern Turkish theatre, with a number of his students going on to distinguished careers as actors, directors and playwrights."

"...an American called Hilary Sumner-Boyd, who was secretary, and for all I could ever discover, the only member of the Oxford Trotskyist party. His extreme gentleness of manner belied the ferocity of his ideas." -- A.J. Ayer

"Hilary Sumner-Boyd (1910-76) was born in Boston, Mass., and educated privately there and at Christ Church, Oxford. He spoke Greek, German, French, Turkish and the Latin languages. His father had known John Reed and Trotsky appears to have been acquainted with his mother. He was business manager of The Red Flag, of the Marxist League and his flat at 238 Edgware Road, a centre for League activities (The Times, 18 Sept. 1976; L.
