Jeremias Drexel was born in Augsburg and was raised as Lutheran. However, he was converted to Catholicism in his youth and educated by the Jesuits before entering the Jesuit Order. He taught the Jesuit seminarians at Dillingen as professor of rhetoric, and then for 23 years he was a court preacher to Maximilian I, the prince-elector of Bavaria in the Holy Roman Empire. It is said that his voice was strong enough to be heard in every corner of the church and that his sermons were such that an hour would seem like a few minutes. During this period he accompanied Maximilian on his Bohemian campaign.
