(bapt. Haarlem, 1 Oct. 1620; d Amsterdam, 18 Feb. 1683). Dutch painter, active mainly in Haarlem but also in Amsterdam. Berchem was the son of the still-life painter Pieter Claesz., and it is not known why he adopted a different surname. Claesz. was his first teacher, but although Berchem tried his hand at most subjects, no still lifes by him are known. His speciality was the Italianate pastoral landscape, and among his contemporaries only Jan Both rivalled his fame in this field.
