Agassiz, Louis Jean Rodolphe (1807-73): entered a college at Bienne at the age of ten, and from 1822 to 1824 he was a student at the Academy of Lausanne. Agassiz afterwards spent some years as a student in the Universities of Zurich, Heidelberg, and Munich, where he gained a reputation as a skilled fencer. It was at Heidelberg that his studies took a definite turn towards Natural History. He took a Ph.D. degree at Erlangen in 1829. Agassiz published his first paper in "Isis" in 1828, and for many years devoted himself chiefly to Ichthyology. During a visit to Paris he became acquainted with Cuvier and Alexander von Humboldt; in 1833, through the liberality of the latter, he began the publication of his "Recherches sur les Poissons Fossiles," and in 1840 he completed his "Etudes sur les Glaciers." In 1846 Agassiz went to Boston, where he lectured in the Lowell Institute, and in the following year became Professor of Geology and Zoology at Cambridge. During the last twenty-seven years of his life Agassiz lived in America, and exerted a great influence on the study of Natural History in the United States. In 1836 he received the Wollaston Medal of the Geological Society of London, and in 1861 he was selected for the Copley Medal of the Royal Society. In 1873 Agassiz dictated an article to Mrs. Agassiz on "Evolution and Permanence of Type," in which he repeated his strong conviction against the views embodied in the "Origin of Species."
