In the world of science many Jews have attained eminence as original investigators and as university professors. Professor Albert Abraham Michelson (b. in Strelno, Germany, 1852) was brought as a child to San Francisco, and was from there appointed to the U. S. Naval Academy at Annapolis, Md., graduating in 1873. He was an instructor in physics and chemistry at the Naval Academy in 1875–9, and was in the office of the Nautical Almanac in Washington until 1880, when he resigned from the United States Navy. After spending several years studying in Germany and France he became professor of physics at the Case School of Applied Science in Cleveland, O. (1883–9). For the following three years he occupied a similar position at Clark University, in Worcester, Mass. Since 1892 he has been professor and head of the department of physics in the University of Chicago. He is a member of various learned societies here and abroad, including a corresponding membership in the Academy des Sciences of the Institute de France. He won numerous prizes and medals for his great scientific achievements, some of which, like the Copley Medal, awarded by the Royal Society of London, and the Nobel Prize for physics (both in 1907), indicate that he is recognized as one of the greatest scientists of the age. He is best known as the discoverer of a new method for determining the velocity of light. His younger brother, Charles Michelson (b. in Virginia City, Nev., 1869), editor of the “Chicago American,” and their sister, Miss Miriam (b. in Calaveras, Cal., 1870), is a dramatic critic and has also written numerous short stories and several novels. Maurice Bloomfield (b. in Bielitz, Austria, 1855), who was brought here at the age of twelve, is a prominent Sanskrit scholar and is recognized as the chief living authority on the Atharva Veda. He has written several important works on his special subjects, and has been professor of Sanskrit and Comparative philology at Johns Hopkins University in Baltimore, Md., since 1881. Jacob H. Hollander (b. in Baltimore, 1871), who was appointed by President McKinley special commissioner to Porto Rico and later treasurer of that island colony, is professor of political ♦economy at the same university. Professor Hollander was appointed by President Roosevelt United States special agent on taxation in Indian Territory (1904), and was in the following year sent as special commissioner to the Republic of San Domingo to investigate its public debt, and was the confidential agent of the Department of State with respect to Dominican affairs. Since 1908 he has been the financial adviser of the Dominican Republic. Professor Hollander takes an active interest in Jewish affairs, and has contributed valuable papers on Jewish history to the publications of the American-Jewish Historical Society, of which he is an officer.
