Nathaniel William Taylor (June 23, 1786 – March 10, 1858) was an influential Protestant Theologian of the early 19th century, whose major contribution to the Christian faith (and to American religious history), known as the New Haven theology or Taylorism, was to line up historical Calvinism with the religious revivalism of the time (The Second Great Awakening). A graduate of Yale College, he returned to found the school's first independent division, the Theological Department, an institution which later became the Yale Divinity School.
