Jean-Baptiste le Rond d'Alembert[a] (/ˌdæləmˈbɛər/ DAL-əm-BAIR;[1] French: [ʒɑ̃ batist lə ʁɔ̃ dalɑ̃bɛʁ]; 16 November 1717 – 29 October 1783) was a French mathematician, mechanician, physicist, philosopher, and music theorist. Until 1759 he was, together with Denis Diderot, a co-editor of the Encyclopédie.[2] D'Alembert's formula for obtaining solutions to the wave equation is named after him.[3][4][5] The wave equation is sometimes referred to as d'Alembert's equation, and the fundamental theorem of algebra is named after d'Alembert in French.
