**Doppelmayr** entered the Aegidien Gymnasium in Nuremberg in 1689. The Aegidien Gymnasium had been founded in the 16th century by the Swiss Protestant reformer Ulrich Zwingli. Doppelmayr was to return to this Gymnasium as a professor later in his career.

From Nuremberg Doppelmayr went to the University of Altdorf where he studied law, mathematics and natural philosophy. Four years later he studied at the University of Halle, then spent 2 years travelling in Germany, Holland and England.

He studied at Utrecht, Leyden, Oxford and London during his travels. Doppelmayr clearly made a good impression on people during these visits since he was elected to membership of a number of scientific societies including the Berlin Academy, St Petersburg Academy and the Royal Society.

Doppelmayr was appointed professor of mathematics at the Aegidien Gymnasium in Nuremberg in 1704 and he remained there for the rest of his life.

Doppelmayr wrote on astronomy, spherical trigonometry, sundials and mathematical instruments. He has a book of tremendous value giving biographical details of 360 mathematicians and instrument makers of Nuremberg from the 15th to the 18th Century.
