Jean Trembley (April 13, 1749 – September 18, 1811), born at Geneva and died in Le Mas-d'Agenais, was a Genevan[1] mathematician who contributed to the development of differential equations, finite differences, and the calculus of probabilities.
Nephew of the naturalist Abraham Trembley, Jean Trembley first studied law in Geneva, before turning to astronomy under the direction of Jacques-André Mallet, director of the Geneva Observatory.
He also traveled in the Alps with Horace-Bénédict de Saussure and made with him his doctoral dissertation on the theory of generation (1767).
In it, he advocated the views of Charles Bonnet, whose disciple he always pretended to be in the fields of philosophy and psychology.
[2] He made part of his career in Berlin, where he was a member of the Prussian Academy of Science and Letters.
