Stephen Jay Gould (b. 1941) is a biologist, geologist and historian of science at Harvard, but he may be best known for his long-running series of reflective articles in Natural History in which he has articulated his view of evolution. In 1972, working with Niles Eldredge, he developed his idea of "punctuated equilibrium".
