LOGAN 712 LOGAN Infectious Diseases;" and edited the works of General John A. Logan. Dr. Logan was largely instrumental in de- veloping the coal field of northern Kansas; he succeeded in securing a franchise, going to Washington for the purpose, so that a bill was passed giving the company which had been organized "the right to purchase twenty acres in fee-simple of the Fort Leavenworth Government Reservation . . . together with the exclusive right to mine for all coal under that Reservation, embracing about 7,000 acres of land." The result was the great output of cheap fuel to the people of Leavenworth and the consequent impetus given to manufac- turing industries in that section. In 1873 President Grant nominated Dr. Lo- gan as minister to Chile, and his mission was so satisfactory and he was held in such esteem that he was chosen to arbitrate between Chile and other governments. In 1879 he became minister to Central America, and in 1883 was re-appointed minister to Chile, holding this position until 1885. His health became im- paired and he returned to the United States, but did not take up a permanent residence, usually spending his summers with his daugh- ter in Canada and winters in Washington or in California. Dr. Logan married Zoe Shaw in 1854 ; they had two children. He died at Los Angeles, California, January 30, 1899, of Bright's disease. Howard A. Kelly. Article by Mr. Edgar S. Murray. Portrait. Private information from Mrs. Charles H. Water- ous (formerly Celia Logan), Dr. Logan's daugli- ter. Logan, George (1753-1821) George Logan, son of William and grand- son of James Logan, the distinguished friend and secretary of William Penn, was born at Stenton, near Philadelphia, September 9, 1753. His mother was Hannah Emlen. He was sent to England for his education when very young, and, on his return, served an appren- ticeship with a merchant of Philadelphia. He had early a great desire to study medicine, which he undertook after he had attained to manhood. He received his M. D. at the Uni- versity of Edinburgh in 1779, then visited France, Germany and Italy, and returned to his own country in 1780. He applied himself for some years to agri- culture, and was known as a skilful agricul- turist. In 1781 he married Deborah, daughter of Charles Norris, an influential and wealthy citizen of Philadelphia. They had three sons, Albanus Charles, Gustavus George and Al- gernon Sydney. He also served in the Legislature. In June, 1798, he embarked for Europe for the pur- pose of preventing a war between France and America. For this step he was violently de- nounced by hostile partisans, but he perse- vered and succeeded in his intentions. He was a Senator from Pennsylvania in the Con- gress of the United States, from 1801 to March, 1807. In 1810 he visited England— as formerly France — with the same philan- thropic desire of preserving peace between the two countries. He was exceedingly grieved at the war which followed, his health gradually declined for some years, and he died April 9, 1821. Information from Dr. Ewing Jordan. Memoir of Dr. George Logan of Stenton, by his widow D. N. Logan., Phila., 1899.

The boy was educated in his native city and graduated from the South Carolina Medical College in 1853, practising but a few months in Charleston, where he was appointed assistant demonstrator of anat- omy in his alma mater. A year later he be- came professor of anatomy and lectured on surgery in the summer school until the out- break of the Civil War, when he volunteered his services to the Confederacy. In 1865 and 1866 he resumed his duties in the chair of anatomy and surgery at the South Carolina Medical College and the fol- lowing summer became professor of anatomy in the Medical College of Richmond, Virginia, accepting the chair of surgery in the New Orleans School of Medicine the next year. In 1867 he was dean of that school and pro- fessor of anatomy and clinical surgery in the University of Louisiana in 1872. He was pe- culiarly fitted for teaching and his clinical lectures and operations were of the highest rank. He was one of the editors of "Geddings Surgery," published in 1858. Dr. Logan was president of the New Or- leans Academy of Medicine in 1872 and of the New Orleans Medical and Surgical As- sociation in 1876 and a member of the South Carolina Medical Society.
