PUGH, Evan, chemist, born in East Nottingham, Pennsylvania, 29 February, 1828; died in Bellefonte, Pennsylvania, 29 April, 1864. He was early apprenticed to the blacksmith's trade, but at the age of nineteen bought out the residue of his time and studied at the Whitestown, New York, seminary, meanwhile supporting himself by manual labor. Falling heir to a small property in his native town, including a school, he taught there successfully for several years. In 1853 he disposed of these interests and went abroad, where for four years he studied natural science and mathematics in the universities of Leipsie, Gottingen, Heidelberg, and Paris, receiving in 1856 the degree of Ph.D. at the University of Gottingen. After this he devoted attention to agricultural chemistry, and made in England a series of valuable determinations of nitrogen, showing that plants do not assimilate free nitrogen. In 1859 he returned to the United States and accepted the presidency of Pennsylvania agricultural college. He at once organized a new scheme of instruction, planned and superintended the erection of the college buildings, secured endowments, and, besides taking the general guidance of the institution, had special charge of the practical investigations of the students in chemistry, scientific agriculture, mineralogy, and geology. This office he held until his death. Dr. Pugh was a fellow of the London chemical society, a member of scientific societies in the United States, and contributed to scientific literature.
