Biography
A native of
Nuremberg , Wurzelbauer was a merchant who became an astronomer. As a youth, he was keenly interested inmathematics andastronomy but had been forced to earn his living as a merchant. He married twice: his first marriage was to Maria Magdalena Petz (1656-1713), his second to Sabina Dorothea Kress (1658-1733). Petz bore him six children.He first published a work concerning his observations on the
great comet of 1680, and initially began his work at a private castle-observatory on Spitzenberg 4 owned by Georg Christoph Eimmart (completely destroyed duringWorld War II ), the director of Nuremberg's painters' academy. Wurzelbauer was 64 when he began this second career, but proved himself to be an able assistant to Eimmart. A large quadrant from his days at Eimmart's observatory still survives.After 1682, Wurzelbauer owned his own astronomical observatory and instruments, and observed the transit of Mercury,
solar eclipse s, and worked out the geographicallatitude of his native city. After 1683, he had withdrawn himself completely from business life to dedicate himself to astronomy.By 1700, Wurzelbauer had become the most well-known astronomer in
Nuremberg . For his services to the field of astronomy, he was ennobled in 1692 byLeopold I, Holy Roman Emperor and added the "von" to his name. He was a member of the French and the Prussian academies of the sciences.Wurzelbauer crater, on the
Moon , was named after him around 1800 by the astronomerJohann Hieronymus Schröter .Works
