(June 24, 1744, Amsterdam - January 28, 1831, Haarlem), was a Dutch painter and the concierge of the Teylers Museum. According to the RKD he learned to paint while working for the decorative wall paper factory of J. Remmers in Amsterdam. From 1786 to 1819 he was the second concierge ("kastelein") of the Teyler's Stichting in Haarlem, where he lived at the "Fundatiehuis" as curator of the art collection, with his studio in the old drawing room of Teyler's drawing academy, which had itself been moved to the city hall. He assumed the position in 1785 after his predecessor Vincent Jansz van der Vinne had left in disagreement with Martin van Marum, the head of the fossil and instrument collections. As curator, he managed to purchase an important collection of Italian drawings from the collection of Queen Christina of Sweden in 1790. He is known for portraits, landscapes, and flower still lifes in the manner of Jan van Huysum.
