Hendrick Gerritsz. Pot
(c. 1580 – 15 October 1657)

Hendrik Gerritsz Pot was a Dutch Golden Age painter, who lived and painted in Haarlem, where he was an officer of the militia, or schutterij. Dutch artist Frans Hals painted Pot in militia sash in Hals' The Officers of the St Adrian Militia Company in 1633. Pot is the man reading a book on the far right. Pot was probably a pupil of Karel van Mander, as was Hals, and they influenced each other. Pot’s paintings were sometimes allegorical in subject and he also painted group schutterstuk portraits, such as The Officers of the St Adrian Militia Company in 1630. He was also influenced by painter and engraver Willem Buytewech.
