Georg Friedrich Brander was born at Regensburg in 1713, and studied mathematics at the university of Altdorf. He founded his workshop at Augsburg, and from 1737 until his death in 1783 he manufactured every type of philosophical, mathematical, and optical instrument. He began to make glass micrometers from 1761, for which he became famous. These were used in microscopy, and also in astronomy. It is thought that Brander's interest in making microscopes was due to the publication at Augsburg in 1754 of the German translation of Henry Baker, Employment for the Microscope (London, 1753).
