Henricus Brucaeus

Heinrich Brucaeus was born in Aalst, Flanders as the son of the patron Gerhard van den Brock.

In 1565, he was employed as a physician of the Maria von Braganza, then joined Rostock Universityas a professor of medicine and astronomy in 1567.

Karl Krause calls Brucaeus a very clever physician and an enormously learned mathematician.

Brucaeus knew the work of Nicholas Copernicus, to whom he gave great respect as a mathematician.

Probably, Tycho Brahe learned the Heliocentrism by Brucaeus during his study stay at the University of Rostock.
