Alexander Emanuel Agassiz (December 17, 1835 – March 27, 1910), son of Louis Agassiz and stepson of Elizabeth Cabot Agassiz, was an American scientist and engineer.-----------------Agassiz was born in Neuchâtel, Switzerland and emigrated to the United States with his father in 1849. He graduated at Harvard University in 1855, subsequently studying engineering and chemistry, and taking the degree of bachelor of science at the Lawrence scientific school of the same institution in 1857; and in 1859 became an assistant in the United States Coast Survey.--------------In 1875 he surveyed Lake Titicaca, Peru, examined the copper mines of Peru and Chile, and made a collection of Peruvian antiquities for the Museum of Comparative Zoology, of which he was curator from 1874 to 1885. He assisted Charles Wyville Thomson in the examination and classification of the collections of the 1872 Challenger Expedition, and wrote the Review of the Echini (2 vols., 1872-1874) in the reports. Between 1877 and 1880 he took part in the three dredging expeditions of the steamer Blake of the Coast Survey, and presented a full account of them in two volumes (1888). In 1896 Agassiz visited Fiji and Queensland and inspected the Great Barrier Reef, publishing a paper on the subject in 1898. Of Agassiz's other writings on marine zoology, most are contained in the bulletins and memoirs of the museum of comparative zoology; but he published in 1865, with Elizabeth Cary Agassiz, his stepmother, Seaside Studies in Natural History, a work at once exact and stimulating, and in 1871 Marine Animals of Massachusetts Bay. Agassiz served as a president of the National Academy of Sciences, which since 1913 has awarded the Alexander Agassiz Medal in his memory. He died in 1910 on board the SS Adriatic en route to New York from Southampton.
