The Napoleon III Telescope is an historic 6-inch refracting telescope owned by the University of Notre Dame. The telescope was given to the university in 1867 by French Emperor Napoleon III[1] and is housed in an observatory on the top of the Nieuwland Hall of Science.[2][3] The objective lens of the telescope was designed by the French physicst Léon Foucault[1] who is best known for a pendulum experiment that demonstrated earth's rotation.[4]
