An odd title but I have added this post in recognition of a little known astronomer from Gdansk in Poland called Johannes Hevelius.  He was born in 1611 and was a great observational astronomer.  He mapped the Moon and catalogued over a thousand stars. He worked for a while at his family’s brewery in Gdansk before concentrating on astronomy.  If you are ever in Poland and see a bottle of Hevelius beer than you know who it is named after.  For more details see this website:  Link to more information.
