Hugh Kingsmill Lunn (21 November 1889 – 15 May 1949), who dropped his last name for professional purposes, was a versatile British writer and journalist. Writers Arnold Lunn and Brian Lunn were his brothers.
Hugh Kingsmill Lunn was born in London and educated at Harrow School and the University of Oxford. After graduating he worked for a brief period for Frank Harris, who edited the publication Hearth and Home in 1911/2, alongside Enid Bagnold; Kingsmill later wrote a debunking biography of Harris, after the spell had worn off. He began fighting in the British Army in World War I in 1916, and was captured in France the next year. He was held as a prisoner of war at Mainz Citadel with, among others, J. Milton Hayes and Alec Waugh.
After the war, he began to write, initially both science fiction and crime fiction. In the 1930s he was a contributor to the English Review; later he wrote a good deal of non-fiction for this periodical's successor, the English Review Magazine. His large output includes criticism, essays and biographies, parodies and humour, as well as novels, and edited a number of anthologies. He is remembered for saying 'friends are God's apology for relations', with a notable flavour of Ambrose Bierce. The dictum was subsequently used by Richard Ingrams for the title of his memoir of Kingsmill's friendships with Hesketh Pearson and Malcolm Muggeridge, two intimate friends whom he influenced greatly.
Muggeridge drew a darker attitude from Kingsmill's sardonic wit. Kingsmill's parody of A. E. Housman's poetry has been recognised as definitive:
