Henry Magee Horricks (4 May 1883 – 17 November 1968) was a Canadian minister, pacifist, and anti-racism activist. In the 1935 Canadian federal election, Horricks also ran as the Co-operative Commonwealth Federation candidate in Calgary West. Henry Horricks attracted an impressive roster of lecturers to the school, including Bishop Paul Jones, H. Richard Niebuhr, A.J. Muste, Harry F. Ward, Sherwood Eddy, Elmore Philpott, Paul Arthur Schilpp, Scott Nearing, Jerome Davis, and many others. Controversially, one of the summer sessions was attended by J.S. Woodsworth.
