He lived in Haarlem, Amsterdam, and Delft, painting portraits and landscapes. He painted staffage in a few paintings for Bartholomeus van Bassen, along with Esaias van de Velde and Anthony Palamedes. In 1626 he moved to The Hague, probably with his father.
He was only active for about a decade from 1630-1641, the period for which there are dated works.
lieutenant is possible that some works from the 1620s are his, but signed with his father"s name before he starting signing with "JM Doctorate. Jonge". This second type of signature led to suppose the existence of another painter M.de Jong.
In 1629 he returned to Haarlem, where he worked until 1645. On November 26, 1633 he became engaged to Philipina Torel in Amsterdam.
