Harry Summerfield Hoff (August 4 1910 - 5 September 2002) was an English novelist, writing under the name William Cooper. He was born in Crewe, and educated at Christ's College, Cambridge. After graduating in 1933, he was teacher in Leicester, the setting for the 'first' novel Scenes from Provincial Life (1950), which would be the first of five featuring the character Joe Lunn.

He served in the Royal Air Force in World War II, and later became a civil servant, associating closely with C. P. Snow, who appears in light disguise as Robert in the Scenes novels. After retiring he held an academic position.

Snow and Hoff evidently discussed the technique of novel writing extensively; and their books show clear parallels, if not in subject matter, where Hoff took the 'low road'. The theme of habit (and also illness) that Snow seems rather consciously to borrow from Proust is used with greater subtlety; while on the other hand the view of people is perhaps deliberately cruder.
