Ruysdael, JACOB (1625?-82), Dutch painter, of whose life little is known. He was born at Haarlem, and studied medicine, but turned to art, and was a pupil of Berchem at Amsterdam. He, in turn, was probably the master of Hobbema. His pictures are mostly landscapes, and he excelled in painting wooded scenes and waterfalls, the figures being generally added by other painters. He is very well represented in the National Gallery.
