April 21, 1109: Anselm, archbishop of Canterbury and one of the most profound thinkers of the Middle Ages, dies around age 76. He attained fame for his argument that faith is the precondition of knowledge ("credo ut intelligam"), his "satisfaction theory" of the atonement ("No one but one who is God-man can make the satisfaction by which man is saved") and for his ontological argument for God's existence.

April 21, 1855: Edward Kimball, a SunDay school teacher in Boston, leads 18-year-old shoe salesman Dwight L. Moody to Christ at the Holton Shoe Store. Moody went on to become the most successful evangelist of his Day (see issue 25: D.L. Moody).
