LATTIMORE, Samuel Allan, chemist, born in Union county, Indiana, 31 May, 1828. He was graduated at Indiana Asbury (now Depauw) university in 1850, and continued as tutor of languages in that institution for two years, becoming in 1852 professor of Greek. In 1860 he was elected professor of chemistry in Genesee college, and in 1867 was called to fill a similar chair in the University of Rochester, where he has since remained, and now (1887) is director of the Reynolds laboratory. Professor Lattimore has also held the offices of chemist to the New York state board of health since 1881, and to the New York state dairy commission since 1886, in which capacities he has accomplished much analytical work tending to the exposure of frauds in various food-products. He has received the degree of Ph. D. from Iowa Wesleyan university and from Depauw university in 1873, and that of LL.D. from Hamilton in the same year. Professor Lattimore is a member of scientific societies, but his publications have been confined to official reports on chemical subjects.
