WILEY, Harvey Washington, chemist, born in Kent, Jefferson County, Indiana, 18 October, 1844. He was graduated at Hanover college in 1867, and was professor of Latin and Greek in 1868-'71 at Butler university, Indianapolis, also studying at Indiana medical college, where he received the degree of M. D. in 1871. After teaching science for a year in the Indianapolis high-school, he entered the Lawrence scientific school at Harvard, where he was graduated with the degree of S. B. in 1873, and then accepted the chair of chemistry at Butler university, which institution gave him the degree of Ph. D. in 1876. He studied chemistry at the University of Berlin in 1878, and during 1874-'83 was professor at the Agricultural college of Indiana (now Purdue university). He also held in 1881-'3 the office of state chemist of Indiana, and in 1883 he was appointed chemist of the United States department of agriculture in Washington, which place he has since held. Professor Wiley is a member of scientific societies, and in 1886 was vice-president of the American association for the advancement of science, with charge of the section of chemistry. He was also in 1886 president of the Chemical society of Washington and of the Association of official agricultural chemists. His work has been chiefly in technology, and more especially in relation to food-products. The subjects of glucose and grape-sugar were very thoroughly studied by him while he was state chemist, and since his appointment in Washington he has investigated sorghum-sugar. Professor Wiley has published presidential and college addresses, and his papers number more than fifty. These include the results of his researches, and have been published in scientific journals, the transactions of societies of which he is a member, and government reports.
