Rupert Brown studied graphic design at art school. At 22 he was the youngest advertising art director in London and then creative director at a premier agency, Evenett & Desoutter.
He began a freelance career, working from Blackheath, S E London for clients including Ford Motor Company, Kodak, Alcan Aluminium, British Telecom, The Observer Newspaper, Jim Henson Publishing.
In 1971 he spent two years converting an 18th century clapboard watermill by the River Stour, on the Essex/Suffolk border, into a house and the old stables into a design and film animation studio. The work expanded to include the designing and editing large format, illustrated books for publishers in the UK and America; a practice that he has continued.
In the late 1980s he began painting, when commercial work allowed, and had three sell-out shows at local galleries. Since then he has sold privately and to commission.
