Richard Benedict Goldschmidt (April 12, 1878 – April 24, 1958) was a German-born American geneticist. He is considered the first to integrate genetics, development, and evolution. He pioneered understanding of reaction norms, genetic assimilation, dynamical genetics, and heterochrony. Controversially, Goldschmidt advanced a model of macroevolution through macromutations that is popularly known as the "Hopeful Monster" hypothesis.
Goldschmidt also described the nervous system of the nematode, a piece of work that later influenced Sydney Brenner to study the wiring diagram of C. elegans, an achievement that later won Brenner and his colleagues the Nobel Prize in 2002.
