EMERSON, Gouverneur, physician, born in Kent County, Del., in 1796; died 2 July 1874. He was graduated in medicine at the University of Pennsylvania in 1816, and began practice in Philadelphia in 1820, but spent many years in retirement on a farm, where he devoted himself to peach culture, and gave much attention to the subject of fertilizers. He wrote extensively on the subject of vital statistics, and contributed to the "American Journal of the Medical Sciences," in 1827'48, tables of the mortality of Philadelphia from 1807 till 1848, showing, among other things, the excessive mortality of males during childhood. He also adapted Cuthbert W. Johnson's " Farmers and Planters' Encyclopaedia of Rural Life" (London, 1842) to the United States (Philadelphia, 1853), and published a translation of Le Play's treatise on the "Organization of Labor." He also contributed numerous scientific papers to the proceedings of the American philosophical society, of which he became a member in 1833.
