SIR See also:CHARLES See also:LYELL (1797-1875)  , See also:British geologist, was the eldest son of See also:Charles See also:Lyell of Kinnordy, See also:Forfarshire, and was See also:born on the 14th of See also:November 1797, on the See also:family See also:estate in See also:Scotland . His See also:father (1767–1849) was known both as a botanist and as the translator of the Vita Nuova and the Convito of See also:Dante: the plant Lyellia was named after him . From his boyhood Lyell had a strong inclination for natural See also:history, especially See also:entomology, a See also:taste which he cultivated at Bartley See also:Lodge in the New See also:Forest, to which his family had removed soon after his See also:birth . In 1816 he entered See also:Exeter See also:College, See also:Oxford, where the lectures of Dr See also:Buckland first See also:drew his See also:attention to See also:geological study . After taking his degree of B.A. in 1819 (M.A. in 1821) he entered See also:Lincoln's See also:Inn, and in 1825, after a delay caused by chronic weakness of the eyes, he was called to the See also:bar, and went on the western See also:circuit for two years . During this See also:time he was slowly gravitating towards the See also:life of a student of See also:science . In 1819 he had been elected a See also:fellow of the Linnean and Geological See also:Societies, communicating his first See also:paper, " On a See also:Recent Formation of Fresh-See also:water See also:Limestone in Forfarshire," to the latter society in 1822, and acting as one of the honorary secretaries in 1823 . In that See also:year he went to See also:France, with introductions to See also:Cuvier, See also:Humboldt and other men of science, and in 1824 made a geological tour in Scotland in See also:company with Dr Buckland . In 1826 he was elected a fellow of the Royal Society, from which in later years he received both the See also:Copley and Royal medals; and in 1827 he finally abandoned the legal profession, and devoted himself to See also:geology . At this time he had already begun to See also:plan his See also:chief See also:work, The Principles of Geology . The subsidiary See also:title, " An See also:Attempt to Explain the Former Changes of the See also:Earth's See also:Surface by Reference to Causes now in Operation," gives the keynote of the task to which Lyell devoted his life . A See also:journey with See also:Murchison in 1828 gave rise to See also:joint papers on the volcanic See also:district of See also:Auvergne and the See also:Tertiary formations of See also:Aix-en-See also:Provence .

After parting with Murchison he studied the marine remains of the See also:

Italian Tertiary Strata and then conceived the See also:idea of dividing this geological See also:system into three or four See also:groups, characterized by the proportion of recent to See also:extinct See also:species of shells . To these groups, after consulting Dr See also:Whewell as to the best nomenclature, he gave the names now universally adopted—See also:Eocene (See also:dawn of recent), See also:Miocene (less of recent), and See also:Pliocene (more of recent); and with the assistance of G . P . See also:Deshayes he drew See also:lip a table of shells in See also:illustration of this See also:classification . The first See also:volume of the Principles of Geology appeared in 1830, and the second in See also:January 1832 . Received at first with some opposition, so far as its leading theory was concerned, the work had ultimately a See also:great success, and the two volumes had already reached a second edition in 1833 when the third, dealing with the successive formations of the earth's crust, was added . Between 183o and 1872 eleven See also:editions of this work were published, each so much enriched with new material and the results of riper thought as to See also:form a See also:complete history of the progress of geology during that See also:interval . Only a few days before his See also:death See also:Sir Charles finished revising the first volume of the 12th edition; the revision of the second volume was completed by his See also:nephew Mr (after-wards Sir) Leonard Lyell; and the work appeared in 1876 . In See also:August 1838 Lyell published the Elements of Geology, which, from being originally an expansion of one See also:section of the Principles, became a See also:standard work on stratigraphical and palaeontological geology . This See also:book went through six editions in Lyell's lifetime (some intermediate editions being styled See also:Manual of Elementary Geology), and in 1871 a smaller work, the Student's Elements of Geology, was based upon it . His third great work, The Antiquity of See also:Man, appeared in 1863, and ran through three editions in one year . In this he gave a See also:general survey of the arguments for man's See also:early See also:appearance on the earth, derived from the discoveries of See also:flint implements in See also:post-Pliocene strata in the See also:Somme valley and elsewhere; he discussed also the deposits of the Glacial See also:epoch, and in the same volume he first gave in his See also:adhesion to See also:Darwin's theory of the origin of species .

A See also:

fourth edition appeared in 1873 . In 1831–1833 Lyell was See also:professor of geology at See also:King's College, See also:London, and delivered while there a course of lectures, whieh became the See also:foundation of the Elements of Geology . In 1832 hemarried See also:Mary (1809–1873) eldest daughter of Leonard See also:Horner (q.v.), and she became thenceforward associated with him in all his work, and by her social qualities making his See also:home a centre of attraction . In 1834 he made an excursion to See also:Denmark and See also:Sweden, the result of which was his Bakerian lecture to the Royal Society " On the Proofs of the See also:gradual Rising of See also:Land in certain Parts of Sweden." He also brought before the Geological Society a paper " On the Cretaceous and Tertiary Strata of Seeland and Moen." In 1835 he became See also:president of the Geological Society . In 1837 he was again in See also:Norway and Denmark, and in 1841 he spent a year in travelling through the See also:United States, See also:Canada and Nova See also:Scotia . This last journey, together with a second one to See also:America in 1845, resulted not only in papers, but also in two See also:works not exclusively geological, Travels in See also:North America (1845) and A Second Visit to the United States (1849) . During these journeys he estimated the See also:rate of recession of the falls of See also:Niagara, the See also:annual See also:average See also:accumulation of alluvial See also:matter in the See also:delta of the See also:Mississippi, and studied those See also:vegetable accumulations in the " Great See also:Dismal Swamp " of See also:Virginia, which he afterwards used in illustrating the formation of beds of See also:coal . He also studied the coal-formations in Nova Scotia, and discovered in company with Dr (afterwards Sir J . W.) See also:Dawson (q.v.) of See also:Montreal, the earliest known landshell, Pupa vetusta, in the hollow See also:stem of a Sigillaria . In bringing a knowledge of See also:European geology to See also:bear upon the extended formations of North America Lyell rendered immense service . Having visited See also:Madeira and See also:Teneriffe in company with G . Hartung, he accumulated much valuable See also:evidence on the See also:age and deposition of See also:lava-beds and the formation of volcanic cones .

He also revisited See also:

Sicily in 1858, when he made such observations upon the structure of See also:Etna as refuted the theory of " craters of See also:elevation " upheld by Von See also:Buch and See also:Elie de See also:Beaumont (see Phil . Trans., 1859) . Lyell was knighted in 1848, and was created a See also:baronet in 1864, in which year he was president of the British Association at See also:Bath . He was elected corresponding member of the See also:French See also:Institute and of the Royal See also:Academy of Sciences at See also:Berlin, and was created a See also:knight of the Prussian See also:Order of Merit . During the later years of his life his sight, always weak, failed him altogether . He died on the 22nd of See also:February 1875, and was buried in See also:Westminster See also:Abbey . Among his characteristics were his great thirst for knowledge, his perfect fairness and See also:sound See also:judgment; while the extreme freshness of his mind enabled him to accept and appreciate the work of younger men . The LYELL See also:MEDAL, established in 1875 under the will of Sir Charles Lyell, is See also:cast in See also:bronze and is to be awarded annually (or from time to time) by the See also:Council of the Geological Society . The medallist may be of any See also:country or either See also:sex . Not less than one-third of the annual See also:interest of a sum of £2000 is to be awarded with the medal; the remaining interest, known as the LYELL GEOLOGICAL FUND, is to be given in one or more portions at the discretion of the Council for the encouragement of geological science .
