| Adam Sedgwick (22 March 1785 – 27 January 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 and continued to be on friendly terms, Sedgwick was an opponent of Darwin's theory of evolution by means of natural selection.
He studied mathematics and theology, and obtained his BA (5th Wrangler) from the University of Cambridge in 1808 and his MA in 1811. His academic mentors at Cambridge were Thomas Jones and John Dawson. He became a Fellow of Trinity College, Cambridge and Woodwardian Professor of Geology at Cambridge from 1818, holding the chair until his death in 1873. An 1851 portrait of Sedgwick by William Boxall hangs in Trinity's collection.
Sedgwick studied the geology of the British Isles and Europe. He founded the system for the classification of Cambrian rocks and with Roderick Murchison worked out the order of the Carboniferous and underlying Devonian strata. These studies were mostly carried out in the 1830s. The investigations into the Devonian meant that Sedgwick was involved with Murchison in a vigorous debate with Henry De la Beche, in what became known as the great Devonian controversy.
Sedgwick investigated the phenomena of metamorphism and concretion, and was the first to distinguish clearly between stratification, jointing, and slaty cleavage. He was elected to Fellow of the Royal Society on 1 February 1821.There is also the:
