St. Peter Canisius was born in 1521, at Nijmegen in Holland. He entered the Society of Jesus, was ordained in 1546, and went to Cologne, where he founded a Jesuit house.

He was a vigorous defender of Catholicism, and published a catechism which was very influential in the Counter-Reformation.

He died in 1597.
