George Gillespie was one of the Scottish commissioners to the Westminster Assembly. He was one of the greatest theologians of all time -- almost singlehandedly steering this august Assembly at certain points. As William Hetherington, in his memoir of Gillespie's life and writings (which is found in Gillespie's two volume Works), notes, "in all those debates no person took a more active part, or gained more distinction than George Gillespie," though he was the youngest man there. Furthermore, Hetherington calls him a "genius of the highest order," and writes that his work "dazzled and astonished his countrymen."
