Johann Fabricius was one of the first astronomers to observe sunspots with a telescope, and the first to publish an account of his observations.
Fabricius was the eldest son among the seven children of famed astronomer, astrologer, and Lutheran Pastor David Fabricius. Johann first studied medicine, mathematics, and astronomy at the University of Helmstedt in 1605, and then enrolled at Wittenberg University the following year. In December 1609 he moved on to Leiden University, where he matriculated as a student of medicine, but was eventually awarded a Magister Philosophiae degree in September 1611.
