Jacob Vosmaer (1574, Delft – 1641, Delft), was a Dutch Golden Age painter.
According to Houbraken he was born in Delft as a descendant of an old line of Vosmeers.[1] He started his career as a landscape specialist, but switched to flowers, which brought him more success.[1] He visited Italy as a young man and returned to Delft in 1608 at the age of 24, where he remained and became a respected citizen, and major in the schutterij.[1] He died in Delft in 1641.[1]
According to the RKD he was the son of the Delft gold- and silversmith Wouter Vosmaer, the brother of the silversmith Arent Wouteresz Vosmaer, the uncle (and teacher) of Arent's son Daniel Vosmaer, and the uncle of Christiaen van Couwenbergh and Abraham Vosmeer.[2] He became a member of the Delft Guild of St. Luke before 1613 and had been a pupil of Jacob de Gheyn II.[2]
