Jan van de Cappelle
b. about 1626 Amsterdam, The Netherlands, d. 1679 Amsterdam, The Netherlands
At his death, Van de Cappelle's estate was worth more than 90,000 guilders, and he left substantial holdings in real estate, as well as a pleasure yacht from which he probably made sketches for his paintings. He assembled one of the finest art collections of his time, which included works by Jan van Goyen, Frans Hals, and Peter Paul Rubens. He owned nine paintings and 1,300 drawings by his likely teacher, seascape painter Simon de Vlieger, and 500 drawings by his friend Rembrandt van Rijn, who painted his portrait.
