HART, Charles Henry, author, born in Philadelphia, Pennsylvania, 4 February, 1847. He received a classical and scientific education, studied law, and was admitted to the bar, 18 November, 1868. Since then, although in active practice, he has devoted much time to literature, he has paid special attention to historical investigation and art matters, until he has become recognized as an authority on the latter subject. He is a member of numerous historical and scientific associations, was elected corresponding secretary of the Numismatic and antiquarian society of Philadelphia, in 1865, and three years later became its historiographer. Much of his literary work has been done in connection with this society. Mr. Hart's separate publications include "Remarks on Tabasco, Mexico" (1865): "Historical Sketch of National Medals" (1866); "Memoir of William Hickling Prescott" (1868); "Bibliographia Lincolniana" with notes, and an introduction, which was subsequently reprinted as "Biographical Sketch of Abraham Lincoln" (Albany, 1870); "Turner, the Dream Painter" (1879); "Bibliographia Websteriana" (1883); and memoirs of William Willis (1870), George Ticknor (1871), Samuel S. Haldeman (1881), Lewis H. Morgan (1883), Lucius Q. C. Ehner (1884), and others. In May, 1870, he delivered a "Discourse on the Life and Services of Gulian C. Verplanck," which was printed. He has in preparation a "Treatise on the Doctrine of Equitable Conversion," based on the English work of Leigh and Dalzell (London, 1825).
