Cornelis Guldewagen (1599 – 1663), was a Haarlem mayor, known best today for his portrait by Frans Hals.
[1][2] Guldewagen was a brewer (brewery "De Vergulde Hart"), but became briefly embroiled in Tulipmania when he and his associate, the Haarlem brewer Johan de Wael (brewery "De Zon"), attempted to transplant 1300 tulip bulbs in February 1637, which caused the crop to fail.
[3] The Guldewagens' son Dammas also became a member of the Haarlem regency, and when he married Judith Loreijn of the brewery "In de Drie Starren", Jan de Bray painted his wedding portrait, and Johannes Cornelisz Verspronck, who used to live across from their house, painted Judith's portrait.
