(VoET), Gysbertus (1588-1676), Dutch theologian, was born at Heusden, Holland. He studied at Leiden, and in 1611 became pastor of Blymen, whence in 1617 he returned to Heusden. In 1619 he played an influential part in the Synod of Dort, and in 1634 was made professor of theology and Oriental science at Utrecht. Three years later he became pastor of the Utrecht congregation. He was an advocate of the extremest form of Calvinism against the Arminia ns; but his personal influence was good, and the city of Utrecht perpetuated his memory by giving his name to the street in which he had lived.
