Danish astronomer.
Protégé of the king of Denmark Frederick II then of the Holy Roman Emperor Rudolf II in Prague.

1569-70
Designed new astronomic instruments that were made in Augsburg, in particular a large celestial globe featuring circles which easily indicated the precision of minutes.
1575-1580
Construction and organisation of the Uraniborg observatory (on the Danish island of Hveen), the largest at the time.
The observatory included a workshop which made high precision instruments- including watches indicating seconds.
