(b. 1508, Amsterdam, d. 1575, Amsterdam)
Netherlandish painter, active in his native Amsterdam and in Antwerp. A pioneer of still life and genre painting, he is best known for scenes that at first glance look like pure examples of these types, but which in fact have a religious scene incorporated in them (Butcher's Stall with the Flight into Egypt, University of Uppsala, 1551). Aertsen was the head of a long dynasty of painters, of whom the most talented was his nephew and pupil Joachim Beuckelaer.
