Marlborough Fine Art was founded in London in 1946 by Frank Lloyd and Harry Fischer. In 1948, the two initial founders were joined by a third partner, David Somerset, the Duke of Beaufort.
By 1952 Marlborough was selling masterpieces of late 19th century including bronzes by Edgar Degas and paintings by Mary Cassatt, Paul Signac, Claude Monet, Camille Pissarro, Alfred Sisley, Auguste Renoir, and drawings by Constantin Guys and Vincent van Gogh.
In 2024 the gallery announced that it would "wind down" all operations. No new art will be taken on, or exhibitions held, but disposing of the large stock will proceed at a gradual pace.
