Jean-Marie Constant Duhamel (/ˌdjuːəˈmɛl/;[1] French: [dy.amɛl]; 5 February 1797 – 29 April 1872) was a French mathematician and physicist.

His studies were affected by the troubles of the Napoleonic era. He went on to form his own school École Sainte-Barbe. Duhamel's principle, a method of obtaining solutions to inhomogeneous linear evolution equations, is named after him. He was primarily a mathematician but did studies on the mathematics of heat, mechanics, and acoustics.[2] He also did work in calculus using infinitesimals. Duhamel's theorem for infinitesimals says that the sum of a series of infinitesimals is unchanged by replacing the infinitesimal with its principal part.[3]
