Antonius Brugmans, portrait

MAR 01 1761

A painted portrait of Anton Brugmans, professor of philosophy and mathematics at Franeker and then Groningen. Brugmans is the man who, in 1778, noticed that a piece of bismuth was pushed AWAY from the pole of a magnet instead of being drawn to it. That single anomalous observation is the first recorded sighting of diamagnetism.
