Peter Harrison and Simon van Oostende met whilst reading history of art and art world practice at Christie’s Education in London. They soon discovered that they shared a deep passion for Old Master pictures, especially those of the sixteenth, seventeenth and eighteenth centuries. Having obtained their degrees, Peter immediately entered the art world interning with Simon Dickinson Ltd and then going on to work for a high end gallery in Mayfair. Simon decided to pursue another degree at the renowned Courtauld Institute of Art, specialising in Early Modern Dutch and Flemish art.

In June 2019, they launched Harrison & van Oostende, specialising in sixteenth, seventeenth and eighteenth-century works of art. Key to their approach in sourcing works is a thorough and extensive level of research and the ability to find pictures of only the highest quality. Consequently, since the launch of the dealership in June 2019, Harrison & van Oostende have sold several artworks to both private clients and museums.
