Elisabeth Catherina Koopmann Hevelius(in Polish also called Elżbieta Heweliusz) (1647–1693) was the second wife of Johannes Hevelius. Like her husband, she was also an astronomer.
Elisabeth Koopmann (or Kaufmann, German: "merchant") was, like Hevelius and his first wife, a member of a rich merchant family in the city of Danzig (Gdansk) located in Pomeranian Voivodeship of the Polish-Lithuanian Commonwealth and a member of the trade organisation called Hansa.
The marriage of the sixteen year old to fifty two year old Hevelius in 1663[1] allowed her also to pursue her own interest in astronomy by helping him manage his observatory. They had a son, who died soon, and three daughters who survived[2]. Following his death in 1687, she completed and published Prodromus astronomiae (1690), their jointly compiled catalogue of 1,564 stars and their positions.
She is considered one of the first female astronomers, and called "the mother of moon charts". Her life was recently novelized as The Star Huntress (2006).
The minor planet 12625 Koopman is named in her honour, as is the crater Corpman on Venus.
