He was born in Rotterdam in 1629 and studied first with the painter, Berchem, at Haarlem. At the age of 24 he entered the service, as painter and valet (!), of one Justice de la Grange, accompanying his master to Delft, The Hague, and Leyden. From 1654 to 1657 he was a member of the painters' guild at Delft where, together with Vermeer and others, he became identified with a group of artists who painted domestic scenes from Dutch life. After his wife's death, he left Delft in 1667 and moved to Amsterdam. Contemporary records show that he was still living there, in poor circumstances, in 1683.
That is about all we know of the life of Pieter De Hooch.
