In the period 1614–1618, Altdorf was briefly the centre of Socinianism in Germany. Encouraged by the connections of German Antitrinitarians to the Racovian Academy in Poland, German and Polish Socinians attempted to establish in Altdorf a similar Academy.[2] Among the notable Socinian students was the 26-year-old Samuel Przypkowski. He was admitted as student on March 22, 1614, three weeks after Thomas Seget, but was expelled from Altdorf in 1616[3] "Crypto-Socinianism" was widely suspected among the student body. In January 1617 the syndicus Jacob Weigel brought two students Joachim Peuschel and Johann Vogel back to Altdorf and the college made them give a public recantation. This recantation was answered by Valentin Schmalz, one the German professors of the Academy in Poland.
