Established in 1993 by Simon Dickinson and David Ker, the firm rapidly earned its reputation as a leading London dealership for Old Master & British Paintings, and also opened a gallery in New York. In 1995, Dickinson broadened its scope to include Impressionist & Modern Art under the direction of James Roundell, and shortly thereafter the company expanded further still into secondary market Contemporary Art. Dickinson handles a uniquely broad range of quality artworks, from early Renaissance masters through to blue-chip Contemporary artists.
