Donthorn was born in Norfolk and was a pupil of Sir Jeffry Wyattville. He worked both in the Gothic and Classical styles, but is perhaps best known for his severe Greek Revival country houses - most of which have been demolished. A large number of his drawings are in the RIBA drawings collection, now housed at the Victoria and Albert Museum.
