At age 16, Elisabetha married Johannes Hevelius, who had been widowed the year before. There was a difference in age of 36 years between them.


Unusually well educated for a woman of the era, Elisabetha was of considerable assistance to Johannes in the operation of his observatory in Danzig. Two plates of Machina coelestis show Elisabetha aiding her husband in the observatory.


Elisabetha served as hostess, when Johannes entertained other astronomers of the era, the most noted being Edmund Halley.


After her husband's death, she edited many of his unpublished writings.




Provided great assistance in the operation of Hevelius' observatory.


Edited many of the unpublished works of Hevelius, after his death.

Catherina Elisabetha Koopman Hevelius is one of the earliest woman astronomers for which there are any records. Indeed, according to aerospace scientist engineer and astronomical historian Dr. Dora Musielak, Madame Koopman Hevelius was "the first woman astronomer of which we have a picture showing her observing the heavens."

In recorded history, only two women astronomers predate Madame Koopman Hevelius. The first is Hypatia of Alexandria, who did not have the benefit of a telescope. The second is Maria Cunitia (c. 1604-1664) [Also see asteroid named for Madame Cunitia], the daughter of a Polish physician who published the Urania Propitia in 1650, a collection of astronomical tables based on Kepler's Rudolphine Tables.
