Sedgwick, Adam, 1785-1873

Adam Sedgwick was one of the founders of modern geology. He proposed the Devonian period of the geological timescale. Later, he proposed the Cambrian period, based on work which he did on Welsh rock strata. Though he had guided the young Charles Darwin in his early study of geology, Sedgwick was an outspoken opponent of Darwin's theory of evolution by means of natural selection.
