In 1778 he became president of Yale College and professor of ecclesiastical history there, having insisted that no theological statement be required of him except assent to the Saybrook platform of 1708; in 1780--1782 he was professor of divinity, and he lectured besides on astronomy and philosophy.
Norwich was settled in 1659 by colonists from Saybrook under the leadership of Captain John Mason (1600-1672), who had crushed the power of the Pequot Indians in Connecticut in 1637, and the Rev. James Fitch (1622-1702), who became a missionary to the Mohegans."
One of the most important events in the history of New Haven was the removal hither in October 1716 from Saybrook of the Collegiate School of Connecticut, which developed into Yale University.
