Input: Question: Were Freiburg and Leipzig located in the same country? Passage:He attended schools in Brixen and Innsbruck and served as a nurse during the Franco-Prussian War. In 1871, following his father's wishes, he began studying economics, eventually attending schools in Leipzig, Breisgau and Freiburg, where he was a member of the Corps Suevia Freiburg. His interest in hunting led him to give up his studies and take positions as a game warden and forester, first for the estates of Count Ernst II, then in Schillersdorf, Upper Silesia, for Nathaniel Meyer von Rothschild., but he had to quit due to an illness. After convalescing in Munich an acquaintance, Eduard von Grützner, suggested art as a career, so Pfretzschner studied sculpture with Edmund von Hellmer in Vienna and Ludwig Manzel in Berlin, where he worked from 1891 to 1913, becoming a Professor at the Prussian Academy of Art.
