Dutch painter, part of a family of artists. He studied with Nicolaes Berchem and painted many different subjects, such as portraits, marine scenes, landscapes, history and battle paintings, but was best known for his flower paintings. At his death, Justus I left a collection of 663 paintings, enough to suggest that he may also have been a dealer. Of his ten children, four were painters: Jan van Huysum, Justus van Huysum II (1685-1707), Jacobus van Huysum (1687/89-1740) and Michiel van Huysum (1704-1760). //
