Müller, J F T (Fritz)

Abstract

Fritz Müller (1822–1897), German naturalist, was one of the great Darwinians of the nineteenth century. Educated in math and science in what was then part of Prussia, he emigrated to Brazil in 1852; in the forests and ocean of the province of Santa Catarina, he found a rich diversity of organisms for study, especially marine and freshwater Crustacea, insects and flowering plants. From original observations of morphology, development, physiology and behaviour, he documented the power of natural selection in the evolution of adaptations. He encountered Darwin's in its German translation in 1861, tested its salient points in the Crustacea and endorsed them. Although he and Darwin were half a world apart, they recognised many common interests through correspondence and publications, and Müller became Darwin's closest intellectual kin.
