Kepler began his professional life as a teacher in the Protestant gymnasium at Graz, in

southern Austria. From here he rose to become an imperial courtier and achieved lasting fame

as an innovator in astronomy.

He compelled to leave Graz with other Protestants in 1598, he attached himself to the

court of Emperor Rudolf II (ruled 1576–1612) in Prague, and succeeded Tycho Brahe as

imperial mathematician in 1601.

provincial schoolteacher to become the astrological and astronomical adviser to the

most powerful monarch in the Christian world, although the emperor proved unreliable as a

source of financial support.
