Georg von Peuerbach

Georg von Peuerbach (1423–1461), born at Peuerbach in Upper Austria, studied at the University of Vienna from 1446 and became its leading astronomer. After observing the Moon occult Jupiter in 1451, he lectured in Italy, where Bologna and Padua offered him chairs, before returning to Vienna in 1453.

In 1454 he became court astrologer to King Ladislas V and later imperial astronomer to Frederick III. His lectures on Ptolemaic planetary theory were attended by the young Regiomontanus, who became his pupil and collaborator, and were later printed as the Theoricae Novae Planetarum. He died in 1461.
