'''Sir Charles Lyell, 1st Baronet''', [[Order of the Thistle|KT]], [[Fellow of the Royal Society|FRS]] ([[November 14]], [[1797]] – [[February 22]], [[1875]]) was a [[Scotland|Scottish]] [[lawyer]], [[geologist]], and protagonist of [[Uniformitarianism (science)|uniformitarianism]]. He was the foremost geologist of his day, and an influence on the young [[Charles Darwin]].
== Life ==
Charles Lyell was born in [[Kinnordy]], [[Forfarshire]] (now [[Angus]]), the eldest of ten children. Lyell's father, also named Charles, was a lawyer and [[botanist]] of minor repute and first exposed the younger Charles to the study of nature. Charles spent much of his childhood at the family’s other home, [[Bartley Lodge]] in the [[New Forest]], [[England]], where his interest in the natural world was sparked.
After being sent down from [[Exeter College, Oxford]] in 1820, Lyell learnt [[geology]] under the wing of the naturalist [[William Buckland]].<ref name="Wilson">Wilson, Leonard G. "Charles Lyell" ''Dictionary of Scientific Biography.'' Ed. Charles Coulston Gillispie. Vol. VIII. Pennsylvania, Charles Scribner's Sons, 1973.</ref> After graduation he took up law as a profession, and completed a circuit through rural England, where he could observe geology. As his eyesight began to fail him he turned to geology as a full time profession.<ref name="Wilson"/> His first paper, "On a recent formation of freshwater limestone in Forfarshire", was presented in 1822.<ref name="Wilson"/> By 1827, he had abandoned the law and embarked on a geological career that would result in fame and the acceptance of ideas, mainly uniformitarianism, proposed by [[James Hutton]] a few decades earlier.<br />
In 1832, Lyle married Mary Horner of Bonn, daughter of Leonard Horner (1785-1864), also associated with the [[Geological Society of London]]. The new couple spent their honeymoon in Switzerland and Italy on a geological tour of the area.<ref name="Macomber">Macomber, Richard W. "Lyell, Sir Charles, Baronet." ''The New Encyclopedia Britannica'', Encyclopedia Britannica, Inc., 1997.</ref><br />
During the 1840s, he traveled to the [[United States]] and [[Canada]], and wrote two popular travel-and-geology books: ''Travels in North America'' (1845) and ''A Second Visit to the United States'' (1849). After the [[Great Chicago Fire]], Lyell was one of the first to donate books to help found the [[Chicago Public Library]].
Lyell's wife Mary died in 1873, and two years later Lyell himself died as he was revising the twelfth edition of ''Principles''. He is buried in [[Westminster Abbey]].<ref name="Macomber"/> Lyell was rewarded by the State with a knighthood ([[Order of the Thistle|KT]]), and later by a baronetcy ([[Baronet|Bt]]), which is an hereditary honour. He was awarded the [[Copley Medal]] in 1858 and the [[Wollaston Medal]] in 1866. [[Lyell (lunar crater)|Lyell crater]] on the [[Moon]] and a [[Impact crater|crater]] on [[Mars]] were named in his honour. In addition, [[Mount Lyell]] in western Tasmania, Australia, located in a profitable mining area, bears Lyell’s name.
== Career and major writings ==
[[Image:Charles Lyell - Project Gutenberg eText 16935.jpg|frame|Charles Lyell in his later years.]]
Lyell supported himself by writing books about his scientific work. He came from a prosperous family, worked briefly as a lawyer in the 1820s, and held the post of Professor of Geology at [[King's College London]] in the 1830s, but from 1830 onward his books provided both a comfortable living and growing fame. Each of his three major books was a work continually in progress. All three went through multiple editions during his lifetime, and Lyell used almost every edition as an opportunity to incorporate additional material, rearrange existing material, and revisit old conclusions in light of new evidence. These frequent, substantial revisions added significant value to new editions of Lyell's books, and helped to ensure robust sales to both the scientific community and the general public.
''[[Principles of Geology]]'', Lyell's first book, was also his most famous, most influential, and most important. First published in three volumes in 1830-33, it established Lyell's credentials as an important geological theorist and introduced the doctrine of [[Uniformitarianism (science)|uniformitarianism]]<ref>http://evolution.berkeley.edu/evolibrary/article/_0/history_12. Accessed 27 Nov. 2007.</ref>
[[Image:Lyell Principles frontispiece.jpg|thumb|220px|The frontispiece from ''Principles of Geology'']]
The central argument in ''Principles'' was that "the present is the key to the past:" That geological remains from the distant past can, and should, be explained by reference to geological processes now in operation and thus directly observable. Lyell's interpretation of geologic change as the steady accumulation of minute changes over enormously long spans of time was also a central theme in the ''Principles'', and was a powerful influence on the young [[Charles Darwin]]. Lyell asked [[Robert FitzRoy]], captain of [[HMS Beagle|HMS ''Beagle'']], to search for erratic boulders on the [[Second voyage of HMS Beagle|survey voyage of the ''Beagle'']], and just before it set out FitzRoy gave Darwin Volume 1 of the first edition of Lyell's ''Principles''. When the ''Beagle'' made its first stop ashore at [[Santiago, Cape Verde|St Jago]] Darwin found rock formations which seen "through Lyell's eyes" gave him a revolutionary insight into the geological history of the island, an insight he applied throughout his travels. While in [[South America]] Darwin received Volume 2 which firmly rejected the idea of organic [[evolution]], proposing "Centres of Creation" to explain diversity and territory of species. Darwin's ideas gradually moved beyond this, but in geology he was very much Lyell's disciple and sent home extensive evidence and his own original theorising, including ideas about the formation of [[atoll]]s, which supported Lyell's uniformitarianism. The ''Beagle'' returned at the start of October 1836. Lyell invited Darwin to dinner on [[29 October]] [[1836]] and from then on they were close friends. Although Darwin tentatively discussed evolutionary ideas with him from 1842, Lyell continued to firmly reject the idea of organic evolution in each of the first nine editions of the ''Principles''. He encouraged Darwin to publish, and following the 1859 publication of ''[[On the Origin of Species]]'', Lyell finally offered a tepid endorsement of evolution in the tenth edition of ''Principles''.
''[[Elements of Geology]]'' began as the fourth volume of the third edition of ''[[Principles of Geology|Principles]]'': Lyell intended [[Elements]] to act as a suitable field guide for students of geology.<ref name = "czscax">Bailey, Edward F.R.S. Charles Lyell: A Biography. Garden City, New York. Doubleday & Company, Inc., 1963.</ref>. The systematic, factual description of geological formations of different ages contained in ''Principles'' grew so unwieldy, however, that Lyell split it off into a single volume under the ''Elements'' title in 1838. The book went through six editions, eventually growing to two volumes and ceasing to be the inexpensive, portable handbook that Lyell had originally envisioned. Late in his career, therefore, Lyell produced a condensed version titled ''Student's Elements of Geology'' that fulfilled the original purpose.
''[[Geological Evidences of the Antiquity of Man]]'' brought together Lyell's views on three key themes from the geology of the [[Quaternary Period]] of Earth history: glaciers, evolution, and the age of the human race. First published in 1863, it went through three editions that year, with a fourth and final edition appearing in 1873. The book was widely regarded as a disappointment because of Lyell's equivocal treatment of [[evolution]]. Lyell, a devout Christian, had great difficulty reconciling his beliefs with [[natural selection]].<ref>Bynum W.F. 1984. Charles Lyell's ''Antiquity of Man'' and its critics. ''J. Hist Biol'' '''17''' 153-87.</ref>
==Scientific contributions==
Lyell's geological interests ranged from [[volcano]]es and geological dynamics through [[stratigraphy]], [[paleontology]] and [[glaciology]] to topics that would now be classified as [[archaeology|prehistoric archaeology]] and [[paleoanthropology]]. He is best known, however, for his role in popularising the doctrine of [[Uniformitarianism (science)|uniformitarianism]].
===Uniformitarianism===
From [[1830]] to [[1833]] his multi-volume ''[[Principles of Geology]]'' was published. The work's subtitle was "An attempt to explain the former changes of the Earth's surface by reference to causes now in operation", and this explains Lyell's impact on science. He drew his explanations from field studies conducted directly before he went to work on the founding geology text.<ref name="Wilson"/> He was, along with the earlier [[John Playfair]], the major advocate of [[James Hutton]]'s idea of [[Uniformitarianism (science)|uniformitarianism]], that the earth was shaped entirely by slow-moving forces still in operation today, acting over a very long period of time. This was in contrast to [[catastrophism]], a geologic idea of abrupt changes due to unknown forces, which had been adapted in England to support belief in [[Deluge (mythology)|Noah's flood]]. In various revised editions (twelve in all, through [[1872]]), ''Principles of Geology'' was the most influential geological work in the middle of the 19th century, and did much to put geology on a modern footing. For his efforts he was knighted in [[1848]], then made a baronet in [[1864]].
===Volcanoes and geological dynamics===
[[Image:Vesuvius from plane.jpg|thumb|An aerial photo of Vesuvius]]
Before the work of Lyell, phenomena such as earthquakes were understood by the destruction that they wrought. One of the contributions that Lyell made in ''Principles'' was to explain the cause of earthquakes.<ref name = "byaztm">Adams, Frank D. ''The Birth and Development of the Geological Sciences''. Dover Publications, Inc., 1938.</ref> Lyell, in contrast focused on recent earthquakes (150 yrs), evidenced by surface irregularities such as faults, fissures, stratigraphic displacements and depressions.<ref name = "byaztm"/><br />
Lyell's work on volcanoes focused largely on [[Vesuvius]] and [[Etna]], both of which he had earlier studied. His conclusions supported gradual building of volcanoes, so-called "backed up-building,"<ref name = "czscax"/> as opposed to the upheaval argument supported by other geologists.
===Stratigraphy===
Lyell's most important specific work was in the field of [[stratigraphy]]. From May [[1828]], until February 1829, he traveled with [[Roderick Impey Murchison]] (1792-1871) to the south of [[France]] (Auvergne volcanic district) and to [[Italy]].<ref name = "czscax"/><ref>Stafford, Robert A. ''Scientist of Empire.'' Cambridge, UK. Cambridge University Press, 1989.</ref><ref name="Macomber"/> In these areas he concluded that the recent strata (rock layers) could be categorized according to the number and proportion of marine shells encased within. Based on this he proposed dividing the [[Tertiary]] period into three parts, which he named the [[Pliocene]], [[Miocene]], and [[Eocene]].
===Glaciers===
[[Image:glacier.zermatt.arp.750pix.jpg|thumb|right|250px|Lateral moraine on a glacier joining the Gorner Glacier, Zermatt, Switzerland.]]
In ''Principles of Geology'' (first edition, vol. 3, Ch. 2, 1833)<ref name="Macomber"/> Lyell proposed that [[iceberg]]s could be the means of transport for [[erratics]]. During periods of global warming, ice breaks off the poles and floats across submerged continents, carrying debris with it, he conjectured. When the iceberg melts, it rains down sediments upon the land. Because this theory could account for the presence of diluvium, the word "drift" became the preferred term for the loose, unsorted material, today called "till." Furthermore, Lyell believed that the accumulation of fine angular particles covering much of the world (today called [[loess]]) was a deposit settled from mountain flood water. Today some of Lyell's mechanisms for geologic processes have been disproven, though many have stood the test of time.<ref name="Wilson"/> His observational methods and general analytical framework remain in use today as foundational principles in geology.<ref name="Wilson"/>
===Evolution===
[[Image:Charles Darwin.jpg|left|thumb|Darwin]]
In the second volume of the of the first edition of ''Principles'' Lyell had explicitly rejected the theories of [[Jean Baptiste Lamarck]] on the [[transmutation of species]], maintaining that species were immutable. Later, [[Charles Darwin]] became a close personal friend, and Lyell was one of the first scientists to support ''[[On the Origin of Species]]'', though he did not subscribe to all its contents. Lyell was also a friend of Darwin's closest colleagues, [[Joseph Dalton Hooker|Hooker]] and [[Thomas Henry Huxley|Huxley]], but unlike them he struggled to square his religious beliefs with evolution. This inner struggle has been much commented on. He had particular difficulty in believing in natural selection as the main motive force in evolution.<ref>Bowler P.J. 2003. ''Evolution: the history of an idea''. 3rd ed, California. 129-134, 215 </ref><ref>Mayr E. 1982. ''The growth of biological thought''. Harvard. (esp pp375-381 & 404-8).</ref><ref>Bartholomew M. 1973. Lyell and evolution: an account of Lyell's response to the prospect of an evolutionary ancestry for man. ''Brit J Hist Sci'' '''6''', 261-303.</ref>
[[Image:Alfred Russel Wallace 1862 - Project Gutenberg eText 15997.png|thumbnail|right|150px|A.R. Wallace in 1862.]]
Lyell and Hooker were instrumental in arranging the peaceful co-publication of the theory of natural selection by Darwin and [[Alfred Russel Wallace]] in [[1858]]: each had arrived at the theory independently (Darwin long before Wallace, however). Lyell's data on stratigraphy were important because Darwin thought that populations of an organism changed slowly, requiring "geologic time".
While Lyell did not accept [[evolution]] (descent with modification) at the time of writing the ''Principles'',<ref>Lyell C. 1830-33. ''The principles of geology''. Murray, London. vol 2, 20-21.</ref> two years after the reading of the Darwin-Wallace paper Lyell wrote in his notebook:
:May 3 1860: "Mr. Darwin has written a work which will constitute an era in geology & natural history to show that... the descendants of common parents may become in the course of ages so unlike each other as to be entitled to rank as a distinct species, from each other or from some of their progenitors." <ref>Wilson, Leonard G. (ed) 1970. ''Sir Charles Lyell's scientific journals on the species question''. Yale University Press. p407</ref>
Lyell's acceptance of [[natural selection]], Darwin's proposed mechanism for evolution, was equivocal, and came in the tenth edition of ''Principles''.<ref name="Wilson"/><ref>Desmond A. 1982. ''Archetypes and Ancestors: palaeontology in Victorian London'' Blond & Briggs, London. page 179: "Even Charles Lyell agreed... that 'natural selection was a force quite subordinate to that variety-making or creative power to which all the wonders of the organic world must be referred.' "</ref> ''[[The Antiquity of Man]]'' (published in early February 1863, just before Huxley's ''Man's place in nature'') drew these comments from Darwin to Huxley:
:"I am fearfully disappointed at Lyell's excessive caution" and "The book is a mere 'digest' ".<ref>Burkhardt F. and Smith S. 1982–present. ''The correspondence of Charles Darwin.'' Cambridge, vol 11, 181 & 173.</ref>
Quite strong remarks: no doubt Darwin resented Lyell's repeated suggestion that he owed a lot to [[Lamark]], whom he (Darwin) had always specifically rejected. Darwin's daughter Henrietta (Etty) wrote to her father:
:"Is it fair that Lyell always calls your theory a modification of Lamark's?" <ref>Burkhardt F. and Smith S. 1982–present. ''The correspondence of Charles Darwin.'' Cambridge, vol 11, 223.</ref><ref>Cape, ISBN 1-84413-314-1
Browne, E. Janet 2002. ''Charles Darwin: the power of place. Volume 2 of a biography''. Cape, London. p219</ref>
In other respects ''Antiquity'' was a success. It sold well, and it "shattered the tacit agreement that mankind should be the sole preserve of theologians and historians." <ref>Browne, E. Janet 2002. ''Charles Darwin: the power of place. Volume 2 of a biography''. Cape, London. p218</ref> But when Lyell wrote that it remained a profound mystery how the huge gulf between man and beast could be bridged, Darwin wrote "Oh!" in the margin of his copy. <ref>Bynum W.F. 1984. Charles Lyell's ''Antiquity of Man'' and its critics. ''J. Hist Biol'' '''17''' 153-87.</ref>
===Geological Surveys===
Lyell noted the “economic advantages” that geological surveys could provide, citing their felicity in mineral-rich countries and provinces. Modern surveys, like the [[U.S. Geological Survey]], map and exhibit the natural resources within the country. So, in endorsing surveys, as well as advancing the study of geology, Lyell helped to forward the business of modern extractive industries, such as the coal and oil industry.
