of his sisters, stopping en route in Los Angeles to present some letters of introduction at the University of Southern California, which had been established just seven years earlier. After seeking jobs in the Oakland area for several weeks, he was surprised to receive an offer of a temporary position at USC, and there he taught Latin, history and botany. He also served as co-coach (with Frank Suffel) of the first USC football team in 1888, with the team winning both of its games against a local athletic club. But he departed immediately thereafter, returning to Haverford to earn his master's degree in mathematics in 1889. From 1889 to 1891, he became principal of the Damascus Academy, a Quaker school in Damascus, Ohio, where he also taught several subjects and conducted chapel services and prayer meetings. On August 7, 1889, he married Emma Florence Robbins, who became one of the two other teachers at the academy. In 1891 he returned to teach at the Oak Grove Seminary in Vassalboro, becoming principal in 1893. He enrolled in 1896 at Clark University, intending to study only briefly, but he remained three years and received his doctorate in psychology in 1899. He then taught at the State Normal School in West Chester, Pennsylvania until 1906. Vineland From 1906 to 1918, Goddard was the Director of Research at the Vineland Training School for Feeble-Minded Girls and Boys in Vineland, New Jersey, which was the first known laboratory established to study intellectual disability. While there, he is quoted as stating: "Democracy, then, means that the people rule by selecting the wisest, most intelligent and most human to tell them what to do to be happy." [Italics are Goddard's.] At the May 18, 1910, annual meeting of the American Association for the Study of the Feeble-Minded, Goddard proposed definitions for a system for classifying individuals with intellectual disability based on intelligence quotient (IQ). Goddard used the terms moron for those with an IQ of 51–70, imbecile for those with an IQ of 26–50, and idiot for those with an IQ of 0-25 for categories of increasing impairment. This nomenclature was standard for decades. A moron, by his definition, was any adult with a mental age between eight and twelve. Morons, according to Goddard, were unfit for society and should be removed from society either through institutionalization, sterilization, or both. Goddard's best-known work, The Kallikak Family, was
