Johann Gaspar Spirzheim, a German phrenologist, born at Longwich, near Treves, Dec. 31, 1776, died in Boston, Mass., Nov. 10, 1832. In 1795 the French invasion interrupted his studies at the university of Treves, but he continued them at Vienna. Here he became the most eminent pupil of Gall, whom he afterward aided in the development and popularization of his doctrines. In 1805 he joined him in his travels and lectures in various parts of Europe, settled with him in Paris in 1807, and was intimately associated with him till 1813. He then delivered lectures in London, which were attacked by Dr. John Gordon in the " Edinburgh Review." In reply Spurzheim demonstrated at Edinburgh, before hundreds of Gordon's students, the fibrous character of the brain, which the latter had denied. After residing several years in Paris, he resumed his lectures in Great Britain in 1825, and in 1832 went to Boston, where he delivered several lectures. Besides his share in the most important publications of Gall, and several works of his own in French, he published "The Physiognomical System of Dr. Gall and Spurzheim" (London, 1815); " Outlines of the Physiognomical System " (1815); " View of the Elementary Principles of Education" (Edinburgh, 1821; enlarged ed., London, 1828); " Phrenology in connection with the Study of Physiognomy " (London, 1826); " The Anatomy of the Brain, with a General View of the Nervous System " (1826); "Outlines of Phrenology" (1827); and "Sketch of the Natural Laws of Man" (1828). - See "Memoir of the Life and Philosophy of Spurzheim," by Andrew Carmichael (Dublin, 1833).
