"You, who wish to study great and wonderful things, who wonder about the movement of the stars, must read these theorems about triangles. Knowing these ideas will open the door to all of astronomy and to certain geometric problems."
--De Tringulis Omnimodis
Born Johann Müller, Regiomontanus took his name from the Latinized form of his home town, Königsberg, "King's Mountain." At age 11 he entered the University of Leipzig; three years later he went to the University of Vienna, where he earned a baccalaureate in two years but had to wait until he was 21 to get his his master's.
Regiomontanus collaborated with his teacher Georg von Peuerbach on astronomical and astrological projects. He observed eclipses and comets, manufactured astronomical instruments, and cast horoscopes for the court of Emperor Frederick III.
