Christian Heiden was a mathematical author and instrument-maker, who had studied under Philipp Melanchthon in Wittenberg, before becoming a teacher of mathematics in Nuremberg in 1556. In the same year as he made this quadrant, he presented a sundial to Melanchthon. The reverse of the instrument on display has a Regiomontanus sundial, one of the most sophisticated instruments in this genre of work, similar to the instrument on display by the cosmographer Miniato Pitti.
