Walker, George

, an able mathematician, was born about 1735 at Newcastle upon Tyne, and descended from a family of considerable antiquity. He received the rudiments of his education at the grammar-school of Newcastle under the care of the rev. Dr. Moises, a clergyman of the church of England. At the age of ten he was removed from Newcastle to Durham, that he might be under the immediate direction of his uncle, a dissenting minister; and having decided in favour of the ministry among the dissenters, he was in 1749 sent to one of their academies at Kendal. In 1751 he studied mathematics at Edinburgh under the tuition of Dr. Matthew Stewart, and made a very great progress in that science. In 1752 he studied theology for two years at Glasgow. Returning home, he began to preach, and in 1757 was ordained minister of a congregation of dissenters at Durham. While here he was a frequent contributor to the “Ladies’ Diary,” in which, as we have recently had occasion to notice, most of the mathematicians of the last and present age, tried their skill; and here also he finished his valuable work on the sphere, which was not, however, published until 1775, when it appeared under the title of the “Doctrine of the Sphere,” in 4to. In the end of 1761, or the beginning of 1762, he accepted of an invitation to become pastor at Great Yarmouth, where he carried on his mathematical pursuits, and having contributed some valuable papers to the Royal Society, he was in 1771 elected a fellow of that learned body. In the same year he accepted an invitation from a congregation at Birmingham, but was induced to recede from this engagement, and accept the office of mathematical tutor to the dissenting academy at Warrington, from which he again removed in 1774 to Nottingham, being chosen one of the ministers of a congregation in that town. Here he entered with great zeal into all the political disputes of the times, and always against the measures of government. After a residence of twenty-four years at Nottingham, Mr. Walker went to Manchester, where he undertook the office of theological tutor in the dissenting academy of that town, to which the duties of mathematical and classical tutor being | likewise added, he was soon obliged to resign the whole, in consideration of his age and infirmities. He continued after this to reside for nearly two years in the neighbourhood of Manchester, and was for some time president of the Literary and Philosophical Society of that town, a society which has published several volumes of valuable memoirs, some contributed by Mr. Walker. He then removed to the village of Wavertree near Liverpool, and, in the spring of 1S07, died in London, at the age of seventythree. He was a man of very considerable talents, which appeared to most advantage in the departments of philosophy and the belles lettres, as may be seen in his “Essays on Various Subjects,” published in 1809, 2 vols. 8vo, to which a copious life is prefixed. Some volumes of his “Sermons” have also been published, which probably were suited to the congregations over which he presided, but contain but a very small portion of doctrinal matter, and that chiefly of what is called the liberal and rational kind. ¹
