It is this way of looking at things that gives to Agassiz's writings their literary and popular interest. He was born in Mortier, Canton Fribourg, May 28th, 1807, the son of a clergyman, who sent his gifted son to the Universities of Zürich, Heidelberg, and Munich, where he acquired reputation for his brilliant powers, and entered into the enthusiastic, intellectual, and merry student-life, taking his place in the formal duels, and becoming known as a champion fencer. Agassiz was an influence in every centre that he touched; and in Munich, his room and his laboratory, thick with clouds of smoke from the long-stemmed German pipes, was a gathering-place for the young scientific aspirants, who affectionately called it "The Little Academy." At the age of twenty-two, he had published his 'Fishes of Brazil,' a folio that brought him into immediate recognition. Cuvier, the greatest ichthyologist of his time, to whom the first volume was dedicated, received him as a pupil, and gave to him all the material that he had been collecting during fifteen years for a contemplated work on Fossil Fishes. In Paris Agassiz also won the friendship of Humboldt, who, learning that he stood in need of money, presented him with so generous a sum as to enable the ambitious young naturalist to work with a free and buoyant spirit. His practical career began in 1832, when he was installed at Neufchâtel, from which point he easily studied the Alps. Two years later, after the 'Poissons fossiles' (Fossil Fishes) appeared, he visited England to lecture. Then returning to his picturesque home, he applied himself to original investigation, and through his lectures and publications won honors and degrees. His daring opinions, however, sometimes provoked ardent discussion and angry comment. Agassiz's passion for investigation frequently led him into dangers that imperiled both life and limb. In the summer of 1841, for example, he was lowered into a deep crevasse bristling with huge stalactites of ice, to reach the heart of a glacier moving at the rate of forty feet a day. While he was observing the blue bands on the glittering ice, he suddenly touched a well of water, and only after great difficulty made his companions understand his signal for rescue. These Alpine experiences are well described by Mrs. Elizabeth Gary Agassiz, and also by Edouard Desors in his 'Séjours dans les Glaciers' (Sojourn among the Glaciers: Neufchâtel, 1844). Interesting particulars of these glacial studies ('Études des Glaciers') were soon issued, and Agassiz received many gifts from lovers of science, among whom was numbered the King of Prussia. His zoölogical and geological investigations were continued, and important works on 'Fossil Mollusks,' 'Tertiary Shells,' and 'Living and Fossil Echinoderms' date from this period.
