LOGAN 713 LOGAN Logan, Thomas Muldrup (1808-1876) Thomas Muldrup Logan, sanitarian and climatologist, born in Charleston, South Caro- lina, July 31, 1808, came of a medical family, his father and grandfather having been phy- sicians. His great-great-grandfather, Colo- nel George Logan, who came from Restalrig, Scotland, early in the eighteenth century and settled in Charleston, had a son, William, who married Martha, daughter of the Provincial Governor Daniel of South Carolina. Their son, George Logan, after receiving a medical degree from the University of Edinburgh in 1773, studied two years in Europe and in 1775 married Honoria Muldrup, daughter of the Danish Consul in Scotland, and returned to Charleston to practise ; also, he was physi- cian to the Orphans' Home in Charleston. To benefit his health he traveled to the New England States in 1793, but died in Salem, Massachusetts, leaving, besides his wife, four children, one of whom, George Logan (1778- 1861) was the father of the subject of our sketch. This George Logan was born in Charleston, January 4, 1778, and graduated in medicine at the LInivcrsity of Pennsylvania in 1802 with a thesis entitled "Hepatic State of Fevers." He settled to practice in Charles- ton, but in 1810 became a surgeon in the United States Navy, serving until his resigna- tion in 1829. He returned to Charleston and practised there until his death. He was phy- sician to the Orphans' Home until 1854, and for about twenty years was in charge of the Naval Hospital at Charleston. He wrote "Practical Observations on Diseases of Children" (218 pp., Charleston, 1825). In 1802 he married Margaret White, daughter of Daniel Polk of Wilmington, Delaware ; she became the mother of Thomas Muldrup Lo- gan. In 1834 he married Ann, daughter of Captain George Turner, of Charleston. He died in New Orleans, February 13, 1861. Thomas Muldrup Logan was educated at Charleston College and studied medicine with his father, graduating at the Medical College of South Carolina in 1828 with a thesis on "Salix Nigra" as a succedaneum to the offi- cial Cinchona. He began practice in Charles- ton and in 1832 went to study for a year in London and Paris. ■ In 1833 he was appointed lecturer on materia medica and therapeutics in the Southern School of Medicine, a sum- mer course connected with the Medical Col- lege of South Carolina. With Thomas L. Ogier he began "A Com- pendium of Operative Surgery" (the first number, published in 1834 ; the second in 1836) ; it described operative procedures for the ligation of arteries, with illustrations de- signed and drawn by Logan. In 1843 he moved to New Orleans where he was chosen a visit- ing physician to the Charity Hospital; he gave up this position in 1847 when appointed visiting surgeon to Luzenberg Hospital, which was closed in 1849. Logan moved to San Francisco, California, in January, 1850, settling in the autumn in Sacramento, to ac- quire an excellent practice and the esteem of the community. Here he remained the rest of his life. Logan wrote letters to E. D. Fenner, M. D., published in the Medical Reporter in 1850, describing the climate of California; he de- scribed the hygienic conditions of California in an article contributed to the Nezv Orleans Medical and Surgical Journal (1852-3, ix, 8) ; he wrote articles on climatologj' and meteor- ology published in the Reports of the Smith sonian Institution for 1854-56; four articles on the "History of Medicine in California" went to the California State Medical Journal. In 1858 he presented to the California State Medical Society a report on the "Topography, Meteorology, Endemics and Epidemics of Cali- fornia"; in 1859 he sent to the American Medical Association a report on the "To- pography and Epidemics of California." In 1868 he read before the Sacramento Society for Medical Improvement a paper on the "Medical History of California for the year 1868," and the same jear before the San Francisco Medical Society a paper on "Mush- rooms and Their Poisoning, with Cases" (pub- lished in the Pacific Medical Journal, n. s., ii) ; his address as president of the State Medical Society is published in the Transactions for 1870-1871, containing also his paper on the "Mortality of California;" the Transactions for 1871-1872 published his "Report on the Annual Museum for the Exhibition of the American Medical Association in Philadelphia and the ' Contributions from California." At the meeting in Philadelphia (1872) he was elected president of the Association and when presiding at the St. Louis meeting discussed medical education and state medicine. When the law was passed in 1870 authorizing a State Board of Health, Logan became per- manent secretary and took up such matters as the ventilation of schoolrooms and areas of special diseases. He believed strongly in a National Board of Health, and prepared a bill for Congress to establish a National San- itary Bureau at Washington (published in the second biennial report of the State Board of Health; the third biennial report gives an-
