Caltech began as a vocational school founded in Pasadena in 1891 by local businessman and politician Amos G. Throop. The school was known successively as Throop University, Throop Polytechnic Institute, and Throop College of Technology, before acquiring its current name in At a time when scientific research in the United States was still in its infancy, George Ellery Hale, a solar astronomer from the University of Chicago, founded the Mount Wilson Observatory in 1904. He joined Throop's board of trustees the same year, and soon began developing it and the whole of Pasadena into a major scientific and cultural destination. He engineered the appointment of James A. B. Scherer, a literary scholar untutored in science but a capable administrator and fund raiser, to Throop's presidency in 1908. Scherer persuaded retired businessman and trustee Charles W. Gates to donate $25,000 in seed money to build Gates Laboratory, the first science building on campus.The promise of the lab attracted physical chemist Arthur Amos Noyes to commit to developing the institution. Arther Fleming, Caltech's primary benefactor, who had donated the land for the permanent campus site at California and Wilson, later donated $100,000 to establish a physics facility, the Norman Bridge Laboratory, which succeeded in attracting experimental physicist Robert Andrews Millikan to join the faculty and assist in establishing the college as a center for science and technology.
