R.A. Torrey (1856 - 1928) was a principal architect of American fundamentalism during the late nineteenth and early twentieth centuries. His apologetic style stressed intellect over emotion, and he represented a voice of assurance that appealed to many evangelicals. Torrey preached to over fifteen million persons between 1901 and 1911. In 1910, he became a contributor to and an editor of 'The Fundamentals' - a series of essays mailed free of charge to Protestant ministers that espoused conservative Christianity, the integrity of the Bible, and the truth of traditional doctrines.
