Johannes Sturm studied philosophy and medicine at the Universities of Rostock (1589) and Helmstedt. In Helmstedt he did his magister in 1594. In 1599 he became professor of logic at the University of Greifswald. At the same time, he turned to medicine and, after completing his doctorate in medicine in 1604, worked as a recognized general practitioner. In 1608, Duke Philipp Julius of Pomerania called him to Wolgast as his archiater (personal physician). From 1608 to 1617 he was the duke's personal physician and accompanied him on his trips to Denmark, Kurland and Poland. After the death of Christian Calenus in 1617 he took over his chair for medicine in Greifswald and also his habitation in the former Dominican monastery.
Johannes Sturm undertook the first anatomical section in 1624. He wrote a number of medical papers. Because of a serious illness of the duke he was called to Wolgast again in 1624. Philipp Julius, who did not comply with Storm's orders, died in February of the following year. Johannes Sturm died in November of the same year.
