SIR See also:JOSEPH See also:PRESTWICH (1812-1896)  , See also:English geologist, was See also:born at Clapham, See also:Surrey, on the 12th of See also:March, 1812 . He was educated in See also:Paris, See also:Reading and at University See also:College, See also:London, where under Dr D . See also:Lardner and See also:Edward See also:Turner, he paid See also:special See also:attention to natural See also:philosophy and See also:chemistry, and gained some knowledge of See also:mineralogy and See also:geology . Circumstances compelled him to enter into commercial See also:life, and until he was sixty years of See also:age he was busily engaged in the See also:City as a See also:wine See also:merchant . He devoted all his leisure to geology . His business journeys enabled him to see and learn much of the See also:general geology of See also:England, See also:Scotland and See also:France, and this so effectively that at the See also:time of his See also:death he ranked as the most eminent of See also:British geologists . As See also:early as 1831 he commenced, during See also:holiday visits, to make a study of the See also:coal-See also:field of See also:Coalbrookdale in See also:Shropshire, and the results of his observations were communicated to the See also:Geological Society of London in 1834 and 1836, and embodied in a memoir published in 1838 . His name is, however, especially known in connexion with his researches on the See also:Eocene strata of the London and See also:Hampshire Basins (1846–1857): he defined the See also:Thanet Sands and the See also:Woolwich and Reading Beds, and studied the sequence of deposits and of organic remains and the method of formation of these and the succeeding strata of London See also:clay and Bagshot Beds . So highly appreciated were his essays on the subject that in 1849 he was awarded the See also:Wollaston See also:Medal by the Geological Society of London; and in 1853 he was elected F.R.S . In the course of his observations he was led to study questions of See also:water See also:supply and published in 1851 A Geological Inquiry respecting the Water-bearing Strata of the See also:Country around London, a See also:work that at once became a See also:standard authority; and his extensive knowledge in that respect procured him a seat on the Royal See also:Commission on Water Supply, appointed in 1866 . From 1858 the question of the antiquity of See also:man engaged his attention . On various occasions statements had been made as to the association of See also:flint implements formed by man with the bones of See also:extinct mammals which belonged to more remote periods than those generally assigned for the See also:appearance of the human See also:race on this See also:earth, but the See also:evidence adduced had usually been disregarded by geologists as not affording sufficient See also:proof of the point .

Prestwich, together with Dr See also:Hugh See also:Falconer and See also:Sir See also:John See also:Evans, saw the desirability of a closer examination of the facts, particularly in regard to the implements discovered by See also:Boucher de See also:Perthes in the gravels of the See also:Somme valley; and their investigations in France and England yielded evidence which proved that man existed contemporaneously with the See also:Pleistocene See also:mammalia (Phil . Trans . 1861 and 1864) . In 1865 a Royal Medal was awarded to Prestwich by the Royal Society . In 1866 he was chosen one of the commissioners appointed to inquire into the several matters See also:relating to coal in the See also:United See also:Kingdom; and he subsequently contributed an important See also:Report on the Quantities of Coal, wrought and unwrought, in the Coalfields of See also:Somersetshire and See also:part of See also:Gloucestershire, and another Report on the Probabilities of finding Coal in the See also:South of England (1871) . His researches on the See also:Crag Beds of See also:Suffolk and See also:Norfolk, his report on See also:Brixham See also:Cave, his papers on the Channel See also:Tunnel and the Chesil See also:Bank, among others published during the years 1868-1875, may be mentioned . In 187o he married See also:Grace See also:Anne McCall (nee Milne), niece of Dr H . Falconer, and author of the See also:Harbour See also:Bar and other See also:works (see Essays Descriptive and See also:Biographical, by Grace, See also:Lady Prestwich; edited by L . E . Milne, 1901) . Prestwich retired from business in 1872, and two years later he was invited to take the See also:chair of geology at See also:Oxford, vacant through the death of John See also:Phillips . This See also:post he occupied until 1887 .

During his professorship he wrote his See also:

great work entitled Geology: Chemical, See also:Physical and Stratigraphical (vol. i., 1886; vol. ii., 1888) . On leaving Oxford Prestwich spent his remaining years in his country See also:house, Darent-See also:Hulme, See also:Shoreham, See also:Kent, erected by him in 1869 . There, although seventy-six years of age, he maintained marvellous activity in geological See also:research, devoting his attention to the superficial deposits of the Darent valley, to the occurrence of See also:palaeolithic flint implements in the valleys and of an earlier type since called eolithic, on the See also:chalk See also:plateau of Kent; he likewise dealt generally with the raised beaches and See also:rubble-See also:drift of the south of England and their relation to See also:recent changes of level . His latest publications were Collected Papers on some Controverted Questions of Geology, and On Certain Phenomena belonging to the See also:Close of the Last Geological See also:Period and on their Bearing upon the Tradition of the See also:Flood (1895) . He was knighted in 1896, and died on the 23rd of See also:June in the same See also:year, at Shoreham in Kent . See Life and Letters of Sir See also:Joseph Prestwich, edited by his wife (1899) .
