Peter Canisius

Peter Canisius was a Dutch Jesuit priest known for his strong support for the Catholic faith during the Protestant Reformation in Germany, Austria, Bohemia, Moravia, Switzerland and the British Isles. The restoration of the Catholic Church in Germany is largely attributed to the work there of the Jesuits, which Canisius led. He is venerated in the Catholic Church as a saint and as a Doctor of the Church.
