Georg Tannstetter (1482–1535)
Born 1482 CE, died 1535 CE.
Georg Tannstetter (April 1482 – 26 March 1535), also called Georgius Collimitius, was a humanist teaching at the University of Vienna. He was a medical doctor, mathematician, astronomer, cartographer, and the personal physician of the emperors Maximilian I and Ferdinand I. He also wrote under the pseudonym of "Lycoripensis". His Latin name "Collimitius" is derived from limes meaning "border" and is a reference to his birth town: "Rain" is a German word for border or boundary. Born in Rain am Lech in the Duchy of Bavaria, he studied in Ingolstadt. In 1503, he followed a call of Conrad Celtis to the University of Vienna, where he taught mathematics. He soon became a leading figure amongst the humanists in Vienna. In 1510, he became the personal physician of emperor Maximilian I, who would six years later ennoble him with the predicate "von Thanau". He travelled with his student Joachim Vadian to Buda in 1518. After his earlier work in c. 1527 he edited a map of Hungary, today known as Tabula Hungariae, from the manuscript of Lazarus Secretarius, a Hungarian clerk.
