Jacob van Campen, February 2, 1596–September 13, 1657, was a Dutch painter and architect. Born in Haarlem, he entered the city’s Guild of Saint Luke in 1614 and is believed to have studied painting with Frans de Grebber. A period in Italy introduced him to the architecture of Andrea Palladio, Vincenzo Scamozzi, and classical antiquity.
After returning to the Netherlands, Van Campen became a principal founder of Dutch Classicism. He worked with Pieter Post and was associated with Constantijn Huygens; his major architectural projects included the Mauritshuis, Huis ten Bosch Palace, the Nieuwe Kerk in Haarlem, and Amsterdam’s former town hall, now the Royal Palace.
Van Campen also painted portraits, history subjects, and decorative works, including contributions to the Oranjezaal at Huis ten Bosch. Matthias Withoos was among the artists who worked with him. His paintings are held by the Rijksmuseum, the Mauritshuis, and Museum Amersfoort, while many of his buildings remain prominent monuments in the Netherlands.
