C. Frank Stoop was a Dutch businessman and art collector based in London.
Through his generosity and connections with the Tate Gallery, the gallery received an oil painting by Georges Braque, a number of drawings and sculptures by Henri Gaudier-Brzeska and a further major donation in 1933 after his death of 17 works by modern European artists, including two paintings by Cezanne, pastels by Degas and the first paintings by Picasso to enter the Tate Collection.
