Abraham Trembley (3 September 1710 – 12 May 1784 Geneva) was a Swiss naturalist. He is best known for being the first to study freshwater polyps or hydra and for being among the first to develop experimental zoology. His mastery of experimental method has led some historians of science to credit him as the "father of biology".
Trembley came from an officer's family from Geneva, Switzerland. He was uncle to Charles Bonnet, with whom he corresponded regularly, as well as to René-Antoine Ferchault de Réaumur (1683-1757) and Lazzaro Spallanzani (1729-1799). Trembley acted as tutor to the two children of Count Willem Bentinck (1704-1774), a prominent Dutch politician at the time. The boys were 3 and 6 when Trembley, during lessons in which he went fishing in the ponds outside the house, accidentally discovered the regenerative powers of the Hydra. Those lessons took place at the Count's summer residence of Sorgvliet nearby The Hague. Sketches and drawings of his experiments with the children, made by Cornelis Pronk, are kept in the archives of the town of The Hague, the Netherlands.
While Trembley thought he had discovered a new species, Leeuwenhoek had in fact first published on hydra in a 1702-1703 volume of Philosophical Transactions of the Royal Society, describing them as a type of "animalculum". In his work Leeuwenhoek clearly described the process of budding, as well as tentacles contractility and the presence of cnidocyte batteries on tentacles.
Trembley's findings were published in a groundbreaking book in 1744, Mémoires pour servir à l'histoire d'un genre de polypes d'eau douce, Gebr. Verbeek, Leiden, translated into German in 1791 as Abhandlungen zur Geschichte einer Polypenart des süssen Wassers. The book includes some of the (engraved) drawings of Pronk. His discoveries lead to his membership of the prestigious Royal Academy in London and a correspondent member of the académie des sciences in France. He became also recipient of the Copley medal.
