Johann Gottfried Galle (June 9, 1812 - July 10, 1910) was a German astronomer at the Berlin Observatory who, with the assistance of student Heinrich Louis d'Arrest, was the first person to view the planet Neptune, and know what he was looking at (September 23, 1846). He used the calculations of Urbain Le Verrier to know where to look.
Neptune was predicted by mathematical calculations and first observed on Sept 23, 1846 by Johann Galle, Urbain Le Verrier and John Couch Adams. This was the first time Neptune was observed, as it is not visible with the naked eye.
