Ercole Dembowski

From Wikipedia, the free encyclopedia

Ercole (Hercules) Dembowski (January 12, 1812 – January 19, 1881) was an Italian astronomer.

He was born in Milan. He inherited the title of "Baron" as the son of Jan Dembowski (Dębowski), one of Napoleon's Polish generals. He served in the navy of Austria-Hungary until 1843.

He was a tireless observer of double stars and made tens of thousands of micrometer measurements. In particular, he remeasured many double stars from Friedrich Struve's Dorpat Catalogue, noting how some of them had changed position over the years due to their mutual orbit as binary stars.

He won the Gold Medal of the Royal Astronomical Society in 1878.

Dembowski crater on the Moon is named after him, as well as the minor planet 349_Dembowska.
