    Johann Gottfried Galle (1812-1910). Based on the calculations of Urbain Le Verrier, Galle and his assistant Heinrich Louis d'Arrest at the Berlin Observatory found the planet Neptune. The orbit of Uranus wasn't quite fitting the expected one and Le Verrier thought it was because the gravity of an unknown planet was affecting it.

    Johann Elert Bode (1747-1826). German astronomer and celestial cartographer. He calculated the orbit of Uranus and gave the planet its name - Uranus was the father of Saturn. He is also known for Bode's Law, which isn't a law but a formula that describes the distances of the first seven planets from the Sun. (It doesn't work for Neptune.)

    Caroline Herschel (1750-1848). Caroline Herschel worked with her brother William in compiling the first catalog of nebulae.
