Habrecht began his career as a Doctor of Medicine. He studied mathematics and astronomy, eventually taking on the role of Professor at the University of Strasbourg. In 1625, he constructed a celestial globe that influenced Johannes Kepler’s son-in-law, Jacob Bartsch - who in turn went on to coin the term ‘planisphere’.

Habrecht came from a long family transition of Swiss instrument and clock makers. His family had resided in Strasbourg for decades, and his father was known for having constructed the astronomical clock inside of Strasbourg Cathedral (completed 1574).
