Réaumur, René-Antoine Ferchault de (France 1683-1757)
natural history, technology, entomology


from Wikipedia.org
Although seldom thought of today, Réaumur was in his own time regarded--correctly--as one of the greatest of scientists. Réaumur did productive work on a remarkable range of subjects, including iron and steel technology, slate-working, porcelain manufacture, egg incubation and preservation, the malleability of metals, tin-plating, temperature measurement (he invented both the Réaumur alcohol thermometer and the Réaumur temperature scale), locomotion in invertebrates, insect behavior (especially of bees), parthenogenesis in aphids, lost limb regeneration, digestion in birds (he showed digestion to be primarily a chemical instead of mechanical process), and much more. His efforts brought many new industries to France, where he was so well thought of that he was made director of the French Academy of Sciences no fewer than twelve times, and subdirector nine times. Réaumur was a forward thinker for his period; he was convinced for example that the government should actively fund science (at that time the pursuit of science was generally viewed as personal avocation) and that such investments would be repaid many times over by the results obtained. He was in fact entirely utilitarian in his motives, and even his studies on insect behavior were justified by looking toward their possible practical implications--for example in pest control or various offshoot industries (silk and honey production, etc.).
