Although many credit Loraine Boettner (1901-1990) in The Reformed Doctrine of Predestination (1932) with originating the acrostic for the Five Points of Calvinism known as TULIP, it is believed that the real originator was instead Cleland Boyd McAfee (1866-1944), who did so in 1905 (whose TULIP was a slightly different version than that of Boettner). More widely known for his study of the King James Version of the Bible, and other works, McAfee is a 19th century American Presbyterian worth getting to know.
