Frank Cadogan Cowper: (16 October 1877–1958) was a British artist, described as "The last of the Pre-Raphaelites".
Cowper was born in Wicken, Northamptonshire, son of an author, Frank Cowper, and grandson of the Rector of Wicken. He had a strict religious upbringing in the tradition of the Plymouth Brethren. He first studied art at St John's Wood Art School in 1896 and then went on to study at the Royal Academy Schools from 1897-1902. He first exhibited at the Royal Academy in 1899, and achieved critical success two years later with his An Aristocrat answering the Summons to Execution, Paris 1791 (1901). In 1902, he spent six months studying under Edwin Austin Abbey before travelling to Italy.
He worked in both watercolours and oils, and also worked as book illustrator - providing the illustrations for Sir Sidney Lee's The Imperial Shakespeare. He contributed to a mural in the Houses of Parliament in 1910 along with Byam Shaw, Ernest Board and Henry Arthur Payne.
As art fashion changed Cowper increasingly exhibited his portrait paintings but still continued to produce historical and literary works.
