On that day, Johann Gottfried Galle, an astronomer working at the Berlin Observatory, received a letter from the French mathematician and astronomer Urbain Le Verrier. The latter is known for “discovering Neptune on the tip of his quill,” i.e., for calculating the coordinates of an unknown planet beyond Uranus. In his letter, the French astronomer asked his colleague to look for the planet in the sky. Wasting no time and having obtained the permission from the Director of the observatory, Galle found the planet on the very same night – it was just fifty two seconds away from the location calculated by Le Verrier.
