William Hopkins (1793 – 1866) was an English mathematician and geologist. He is considered a founder of dynamical geology. Hopkins made important contributions in asserting a solid, rather than fluid, interior for the Earth and explaining many geological phenomena in terms of his model.
After meeting Adam Sedgwick in 1833 and joining him in several excursions, Hopkins focused on geology. From then on, in papers published by the Cambridge Philosophical Society and the Geological Society of London, he defined the discipline of physical geology, which involved mathematical investigations dealing with the effects that an upward force, from below, would result in fissures and faults in the region above the upward force. In this way he discussed the elevation and denudation of the Lake District, the Wealden District and the Bas Boulonnais.
