Johnny Van Haeften, born John Henry Van Haeften in 1952 in London, was educated at Eton College where he developed interests in both philately and art. At age 17 he joined Christie's auction house, initially working on the integration of stamp dealers Robson Lowe and in public relations, before transferring to the pictures department in 1975 after six years of persistent effort. In 1977, he节he and his wife Sarah Anne Rowley, whom he married that year, opened their first gallery on Bond Street in London, specialising in Dutch and Flemish Old Master paintings. In 1982, the gallery moved to 13 Duke Street, St. James's, where it remained for 35 years and became a fixture of the West End dealers' community. The Daily Telegraph included it in a 2012 list of London's ten best independent art galleries. In January 2017, the Duke Street gallery closed after the building's owner sold the property and informed Van Haeften that Italian art dealer Fabrizio Moretti would be moving in. Rather than pursue legal action, Van Haeften relocated the business to a refurbished coach house at Beaufort House, his home in Ham, near Richmond, Surrey, where he continues to operate with reduced stock on an appointment-only basis. Over the course of his career, Van Haeften estimated in 2017 that he had sold approximately 4,800 paintings.
