The 'Log College' was a very early
American Presbyterian theological seminary located in what is now
Warminster,
Pennsylvania. It was founded by
William Tennent and his son
Gilbert Tennent and operated from 1726 until William Tennent's death in 1746.
It has been considered to be a predecessor institution of
Princeton University as several of its teachers and graduates served in important posts at Princeton at or soon after its founding in 1746.
