William Fryer Harvey AM (14 April 1885 – 4 June 1937) was an English writer of short stories, most notably in the macabre and horror genres. Among his best-known stories are "August Heat" and "The Beast with Five Fingers", described by horror historian Les Daniels as "minor masterpieces".
Born into a wealthy Quaker family in Yorkshire, he attended the Quaker schools at Bootham in Yorkshire and at Leighton Park in Reading before going on to Balliol College, Oxford. He took a degree in medicine at Leeds. Ill health dogged him, however, and he devoted himself to personal projects such as his first book of short stories, Midnight House (1910).
In World War I he initially joined the Friends' Ambulance Unit, but later served as a surgeon-lieutenant in the Royal Navy, and received the Albert Medal for Lifesaving. Lung damage received during the rescue leading to the award troubled him for the rest of his life, but he continued to write both short stories and his cheerful and good-natured memoir We Were Seven.
Harvey was a practicising Quaker.
Before the war he had shown interest in adult education, on the staff of the Working Men's College, Fircroft, Selly Oak, Birmingham. He returned to Fircroft in 1920, becoming Warden, but by 1925 ill-health forced his retirement. In 1928 he published a second collection of short stories, The Beast with Five Fingers, and in 1933 he published a third, Moods and Tenses. He lived in Switzerland with his wife for much of this time, but nostalgia for his home country caused his return to England. He moved to Letchworth in 1935 and died there in 1937 at the age of 52. After a funeral service at the local Friends Meeting House Harvey was buried in the churchyard of St Mary the Virgin in Old Letchworth.
