Background. Johann Georg Tralles (1763–1822) was a German mathematician and physicist. In 1819, he discovered the Great Comet of 1819, officially designated C/1819 N1. This non-periodic comet was exceptionally bright, approaching an apparent magnitude of 1–2, and was subsequently named Comet Tralles in his honor.
