Pierre Lyonet - Scientist of the Day

Pierre Lyonet, a French illustrator and microscopist, was born July 22, 1708. Lyonet did most of the drawings for Abraham Trembley’s classic Mémoires pour servir à l’histoire d’un genre de polypes d’eau douce (Memoir on fresh-water polyps, 1744), which revealed that tiny Hydra, the miniature medusa-like denizens of swamp water, could regenerate all their missing parts after being cut into pieces (see first image above).

Having earned his spurs at Trembley’s microscope and the drafting table, Lyonet set off on his own, and in 1762 he published Traité anatomique de la chenille qui ronge le bois de saule (Anatomical treatise on the willow caterpillar), which, in numerous engravings, showed every single muscle, nerve, organ, and duct of what we now call the goat-moth caterpillar. The drawings were so detailed that some critics doubted that that such precise observation was possible. In fact, the details were real. Lyonet made his observations with a single-lens microscope of his own design, with the lens suspended on the end of a tiny segmented arm which could be easily moved around over the dissecting table, an integral part of the microscope. In our 2009 exhibition, Singular Beauty, we displayed several single-lens dissecting microscopes, and we also displayed Lyonet’s book, which has an illustration of his microscope (second image), as well as many exquisite engravings of caterpillar innards (third image).

Reaumur’s observations of wasps chewing and spitting out wood to build their papery nests eventually led to the idea of making paper from wood pulp.

"Why am I always sick?" I ask, sitting in my room for days having forgotten to eat or bathe or change clothes. "A mystery of medical science." I say, being around chemicals most of the time and staring at a computer screen the rest of the time for days. "This couldn’t possibly be any of my doing"
