PENDLETON, Edmund Monroe, chemist, born in Eatonton, Georgia, 19 March, 1815; died in Atlanta, Georgia, 26 January, 1884. He was graduated at the Medical college of the state of South Carolina in 1837, and then practised his profession in Warrenton and Sparta, Georgia, for many years. On the organization of Oglethorpe medical college, Savannah, he was elected professor of surgery, but declined the appointment on account of his health. He then turned his attention to agriculture, was the originator of the Pendleton formulas for fertilizers, which have long been successfully used, and was the first to employ animal matter and cotton-seed meal in the manufacture of fertilizers. Dr. Pendle ton was the first to develop the fact that phosphoric acid and nitrogen are the two plant-constituents that are first exhausted from soils by cereals and cotton-culture. In 1872-'7 he held the chair of agriculture and horticulture in the University of Georgia. In the latter year failing health forced him to retire, and he moved to Atlanta, Georgia, where with his son, William M. Pendleton, he founded the Pendleton guano company, of which he was elected chemical director, a place that he held until his death. He contributed to various periodicals in both prose and verse, and his "Scientific Agriculture" (New York, 1874) was extensively used as a text-book in colleges and other institutions of learning.
