Peter Denys DL (1760-1816) was a British drawing master, later patron of the arts and landowner. He was the son of the language teacher Peter Denys (sometimes Denyss), who was himself the son of a Swiss emigrant. Denys was High Sheriff of Northamptonshire in 1812. Denys married his pupil, Lady Charlotte Fermor (1766–1835), daughter of George Fermor, 2nd Earl of Pomfret. With her income of £4,000 a year, he bought Sloane Place in London, and Fremington, Yorkshire. Their son was the politician, Sir George Denys, 1st Baronet (1788-1857).
