Georg Tannstetter

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.

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.

The map was published by Johannes Cuspinianus, printed 1528 in Ingolstadt by Petrus Apianus; its unique copy is in the National Library of Hungary.

Tannstetter is also considered a pioneer of the history of science with his work Viri Mathematici, containing biographies of mathematicians at the University of Vienna from the 15th century.
