Johannes Hevelius


Johannes Hevelius (1611-1687) was a Polish astronomer based in Danzig (Gdańsk). He worked from his own privately funded observatory, creating maps of the Moon's surface, discovering the first variable star, and spotting several new comets. His Prodromus Astronomiae, published posthumously and including many of his own engravings, was the most comprehensive and accurate catalogue of the stars yet compiled.
