GRAY, See also:ASA (1810-1888) , See also:American botanist, was See also:born at See also:Paris, See also:Oneida See also:county, N.Y., on the 18th of See also:November 1810. He was the son of a See also:farmer, and received no formal See also:education except at the See also:Fairfield (N.Y.) See also:academy and the Fairfield medical school. From Dr See also:James See also:Hadley, the See also:professor of See also:chemistry and materia medica he obtained his first instruction in See also:science (1825-1826). In the See also:spring of 1827 he first began to collect and identify See also:plants. His formal education, such as it was, ended in See also:February 1831, when he took the degree of M.D. His first contribution to descriptive See also:botany appeared in 1835, and thereafter an uninterrupted See also:series of contributions to systematic botany flowed from his See also:pen for fifty-three years. In 1836 his first botanical See also:text-See also:book appeared under the See also:title Elements of Botany, followed in 1839 by his Botanical Text-Book for Colleges, See also:Schools, and Private Students which See also:developed into his Structural Botany. He published later First Lessons in Botany and See also:Vegetable See also:Physiology (18J7); How Plants Grow (1858) ; See also:Field, See also:Forest, and See also:Garden Botany (1869); How Plants Behave (1872). These books served the purpose of developing popular See also:interest in botanical studies. His most important See also:work, however, was his See also:Manual of the Botany of the See also:Northern See also:United States, the first edition of which appeared in 1847. This manual has passed through a large number of See also:editions, is clear, accurate and compact to an extraordinary degree, and within its See also:geographical limits is an indispensable book for the student of American botany. Throughout his See also:life Gray was a diligent writer of reviews of books on natural See also:history subjects.

Often these reviews were elaborate essays, for which the books served merely as texts; often they were clear and just summaries of extensive See also:

works; sometimes they were sharply See also:critical, though never See also:ill-natured or unfair; always they were interesting, lively and of See also:literary as well as scientific excellence. The greater See also:part of Gray's strictly scientific labour was devoted to a See also:Flora of See also:North See also:America, the See also:plan of which originated with his See also:early teacher and See also:associate, See also:John See also:Torrey of New See also:York. The second See also:volume of Torrey and Gray's Flora was completed in 1843; but for See also:forty years there-after Gray gave up a large part of his See also:time to the preparation of his Synoptical Flora (1878). He lived at the See also:period when the flora of North America was being discovered, described and systematized; and his enthusiastic labours in this fresh field placed him at the See also:head of American botanists and on a level with the most famous botanists of the See also:world. In 1856 he published a See also:paper on the See also:distribution of plants under the title See also:Statistics of the Flora of the Northern United States; and this paper was followed in 1859 by a memoir on the botany of See also:Japan and its relations to that of North America, a paper of which See also:Sir J. D. See also:Hooker said that " in point of originality and far-reaching results lit] was its author's See also:opus magnum." It was Gray's study of plant distribution which led to his intimate See also:correspondence with See also:Charles See also:Darwin during the years in which Darwin was elaborating the doctrines that later became known as Darwinism. From 1855 to 1875 Gray was both a keen critic and a sympathetic exponent of the Darwinian principles. His religious views were those of the Evangelical bodies in the See also:Protestant See also:Church; so that, when Darwinism was attacked as See also:equivalent to See also:atheism, he was in position to See also:answer effectively the unfounded allegation that it was fatal to the See also:doctrine of See also:design. He taught that " the most puzzling things of all to the old-school teleologists are the principia of the Darwinian." He openly avowed his conviction that the See also:present See also:species are not See also:special creations, but rather derived from previously existing species; and he made his avowal with See also:frank courage, when this truth was scarcely recog ` nized by any naturalists, and when to the clerical mind See also:evolution meant atheism. In 1842 Gray accepted the See also:Fisher professorship of natural history in Harvard University. On his See also:accession to this See also:chair the university had no See also:herbarium, no botanical library, few plants of any value, and but a small garden, which for lack of See also:money had never been well stocked or well arranged.

He soon broughttogether, chiefly by widespread exchanges, a valuable herbarium and library, and arranged the garden; and thereafter the development of these botanical resources was part of his See also:

regular labours. The herbarium soon became the largest and most valuable in America, and on See also:account of the numerous type specimens it contains it is likely to remain a collection of See also:national importance. Nothing of what Gray did for the botanical See also:department of the university has been lost; on the contrary, his labours were so well directed that everything he originated and developed has been enlarged, improved and placed on See also:stable See also:foundations. He himself made large contributions to the See also:establishment by giving it all his own specimens, many books and no little money, and by his will he gave it the royalties on his books. During his See also:long connexion with the university he brought up two generations of botanists and he always took a strong See also:personal interest in the researches and the personal prospects of the See also:young men who had studied under him. His scientific life was mainly spent in the herbarium and garden in See also:Cambridge; but his labours there were relieved by numerous journeys to different parts of the United States and to See also:Europe, all of which contributed to his work on the Synoptical Flora. He lived to a See also:good See also:age—long enough, indeed, to receive from learned See also:societies at See also:home and abroad abundant See also:evidence of their profound respect for his attainments and services. He died at Cambridge, See also:Mass., on the 3oth of See also:January 1888. His Letters (1893) were edited by his wife; and his Scientific Papers (1888) by C. S. See also:Sargent. (C.
