Louis Théodore Frederic Colladon
Louis Théodore Frederic Colladon was a Swiss physician and botanist known for his investigations of the plant genus Cassia. He was the son of pharmacist and amateur botanist Jean-Antoine Colladon.
He studied medicine at the University of Montpellier, where one of his instructors was botanist Augustin Pyramus de Candolle. After graduation, he started a medical practice in Paris. As a physician, he distinguished himself in the treatment of cholera patients during the epidemic of 1832.
Among his written works was a monograph on Cassia titled "Histoire naturelle et médicale des casses, et particulièrement de la casse et des sénés employés en médecine" and a tale involving descent in a diving bell that was published in English as "Narrative of a descent in the diving-bell, &c. &c.". In 1830 the plant genus Colladonia was named in his honor by Augustin Pyramus de Candolle.
