a Dutch designer, draughtsman, and painter, most famous for his marine paintings. In the 1630s and 1640s he was one of the best-known Dutch maritime painters. He moved away from the monochrome style of Jan Porcellis and Willem van de Velde, the elder towards a more realistic use of colour, with highly detailed and accurate representations of rigging and ship construction. He painted ships in harbour and at sea as well as storms and shipwrecks. In addition to painting, he designed tapestries, etchings, stained glass windows for the Nieuwe Kerk in Amsterdam, and the organ screen for the St. Laurenskerk in Rotterdam.
