Tobias Volckmer , also Volkmer and Volkhamer (* between 1550 and 1560 in Braunschweig ; † 1629 presumably in Munich ) was a German mathematician , goldsmith , copper engraver and geodesist who initially worked at the ducal court in Salzburg and for more than three decades in Munich.

Life

Tobias Volckmer came from Braunschweig, where he was born around 1550. Nothing is known about his parents, his youth and his training as a mathematician and goldsmith. In 1586, Volckmer became a citizen of the city of Salzburg as a goldsmith . His son Tobias was born there that same year . It is not known whether Volckmer had any other children. Some of his artfully executed precise mathematical and astronomical devices were created in Salzburg.

Eight years later, on July 12, 1594, Volckmer moved to the court of Duke Wilhelm V of Bavaria in Munich for an annual salary of 200 guilders . In addition to his professional activity, he gave his son Tobias, who was training to be a goldsmith, lessons in geometry and surveying . Together, father and son Volckmer were later involved in the staking out and surveying of the area for today's Munich court garden and in 1616 in the surveying preparation work for the planned brine pipeline from Reichenhall to Traunstein . After his death, his son Tobias succeeded him at the court.

Works

A hand drawing made by Volckmer in 1619 of the salt trade routes to Bohemia , including the Goldene Steig , is in the plan collection of the Bavarian Main State Archives in Munich. The few remaining fine instruments made by Tobias Volckmer the Elder are now in the possession of museums. An astrolabe made in 1591 made of brass and copper with a diameter of 51 centimeters is shown in the Museum für Kunst und Gewerbe in Hamburg , a quadrant from 1608 in the Science Museum Museo Galileo in Florence .
