GOOCH, Frank Austin, chemist, born in Watertown, Massachusetts, 2 May, 1852. He was graduated at, Harvard in 1872, and was an assistant under Professor Josiah P. Cooke in the chemical laboratory until 1875. Subsequently he was associated in the analytical work performed in Newport, Rhode Island, under the authority of the United States geological survey, receiving in 1877 the degree of Ph. D. from Harvard for his original researches. In 1879 he was appointed special agent to the tenth United States census, and was detailed as an expert to make analyses of coals and iron ores. His report on these subjects appears in one of the volumes of the census. From 1881 till 1884 Dr. Gooch was chief chemist of the northern transcontinental survey, and from 1884 till 1886 assistant chemist to the United States geological survey in Washington. In 1886 he was up-pointed professor of chemistry in Yale, and has undertaken the reorganization of that department, which, owing to the development of the Sheffield scientific school, had for some time been neglected. The Kent chemical laboratory at Yale, the construction of which was to have been begun in 1887, was planned by him. Dr. Gooch is a member of scientific societies, and his contributions to chemical literature, though few in number, have been of great value. They consist principally of descriptions of improved methods of analysis, and of new forms of apparatus, including the " Gooch filter," which is now extensively used.
