Elisabetha Hevelius died in Danzig on 22 December 1693.
22 December 1693 marks the death of Elisabetha Catherina Koopman Hevelius in Danzig. Biographical sources agree on the date of death, and one source also notes her burial the following day. Her death ended the life of a woman whose name had long been connected with one of the most celebrated astronomical workshops of the seventeenth century.
Her historical importance did not rest on a single discovery but on a sustained body of work: assisting Johannes Hevelius with observations, helping with data reduction and engraving, and preserving his scientific output after his death. In a century when women’s scientific labor was typically hidden or credited to men, Elisabetha’s posthumous reputation is itself significant. Later historians and reference works increasingly recognized her as one of the earliest documented female astronomers and as a key figure in the publication history of Prodromus astronomiae. Her death closed the final chapter of a partnership that helped shape early modern astronomy in Gdańsk and beyond.
