Louis Théodore Frederic Colladon (25 August 1792 – 25 April 1862) was a Swiss doctor and botanist born in Geneva. He studied medicine at the University of Montpellier, where he learned from botanist Augustin Pyramus de Candolle. After finishing his studies, he practiced medicine in Paris and was noted for treating cholera during the 1832 epidemic. Colladon studied the plant group Cassia and published a monograph, Histoire naturelle et médicale des casses, et particulièrement de la casse et des sénés employés en médecine (1816). He also wrote a tale about a descent in a diving bell, published in English as Narrative of a descent in the diving-bell, &c. &c. (1821). In 1830, Candolle named the plant genus Colladonia in his honor.
