German astronomer remembered for revising Johannes Kepler's Rudolphine Tables. Her Urania propitia siva tabulae astronomicae mire faciles (1650) greatly simplified Kepler's work. Cunitz prefaced the volume by explaining that despite being the work of a woman, the Urania was nevertheless accurate. Her tables proved of great utility and went through many editions. This led many to suspect her husband had computed them. Cunitz's husband wrote a preface for later editions to dispel such rumors.
