August Friedrich Leopold Weismann FRS (For), HonFRSE, LLD (17 January 1834 – 5 November 1914) was a German evolutionary biologist. Fellow German Ernst Mayr ranked him as the second most notable evolutionary theorist of the 19th century, after Charles Darwin.

Weismann also promoted Charles Darwin's 1859 theory of the evolution of species.

Weismann presented in his 1868 paper a long series of biological facts that are consistent with an evolutionary interpretation, but simply make no sense if the living world were the product of a single act of creation. Weismann's attitude toward evolution was close to that of the modern evolutionist, for whom evolution is not a theory but
