Edward Forbes
Résumé
Edward Forbes FRS, FGS (12 February 1815 – 18 November 1854) was a Manx naturalist. In 1846, he proposed that the distributions of montane plants and animals had been compressed downslope, and some oceanic islands connected to the mainland, during the recent ice age. This mechanism, which was the first natural explanation to explain the distributions of the same species on now-isolated islands and mountain tops, was discovered independently by Charles Darwin, who credited Forbes with the idea. He also incorrectly deduced the so-called azoic hypothesis, that life under the sea would decline to the point that no life forms could exist below a certain depth.
Forbes was born at Douglas on the Isle of Man. His father was a well-to-do banker. As a child, Forbes was very interested in collecting insects, shells, minerals, fossils, and plants. Due to poor health, he was unable to attend school from his 5th through his 11th years. In 1828, he started attending the Athole House Academy in Douglas.
In June 1831, Forbes moved to London to study drawing but was not admitted by the Royal Academy. However, having given up on art as a profession, he trained privately and moved back to Douglas. In later years, Forbes used his artistic abilities to create humorous drawings for his publications.
In November 1832, Forbes matriculated as a medical student in the University of Edinburgh attending the lectures of Robert Jameson and Robert Knox while also being active in student societies. In 1832, he studied the natural history of the Isle of Man. Forbes's brother David was a notable mineralogist.
In 1833, Forbes travelled to Norway to study its botanical resources. His findings were published in Loudon's Magazine of Natural History for 1835–1836. The British Association funded his studies based on dredging in the Irish Sea for biological specimens. In 1835, he travelled in France, Switzerland and Germany to study their natural histories.
In 1836, Forbes abandoned his medical studies and moved to Paris, where he attended the lectures at the Jardin des Plantes on natural history, comparative anatomy, geology and mineralogy.
