Ruysdaal (rois'dal) (or Ruysdael), Jacob van. One of the most distinguished Dutch landscape painters. Born at Haarlem, probably about 1625; died in the poorhouse of his native place, 1682. His paintings were little appreciated during his lifetime. Landscapes with dark clouds hanging over them, lakes and rivulets surrounded by overhanging trees, etc., are his subjects, and are represented with the true poetic feeling and admirable technique.
