The first important architectural painter was Dutch Hans Vredeman de Vries (1527-1607), who was both an architect and a painter.[3] Students of Hans Vredeman de Vries, both in Flanders and in the Netherlands, include his sons Salomon and Paul, and Hendrik van Steenwijk I. Through them the genre was popularized and their family and students turned it into one of the main domains of Dutch Golden Age painting.
