René-Édouard Claparède

René-Édouard Claparède (; 24 April 1832, Chancy – 31 May 1871, Siena) was a Swiss anatomist.

The Claparède family was Protestant and originally from Languedoc. They moved to Geneva after Louis XIV's Edict of Fontainebleau in 1685.

He received his education in Geneva and Berlin, where he attended lectures given by Johannes Peter Müller.

His main research dealt with the structure of infusoria, the anatomy of annelids, the histology of earthworms, the embryology of arthropods and the evolution of spiders. Claparède stressed the importance of studying and illustrating living or recently killed organisms and he did not deposit any museum specimens. He died aged 39 from tuberculosis.
