#OnThisDay in 1848, Karl Weierstrass became a mathematics teacher at the Catholic Gymnasium in Braunsberg, Germany, his third such position. That year he taught mathematics for 19 hours per week, took over the geography class after Easter, and received a special note of thanks for helping out in the gym! (@MacTutor)
