DE LEON, David Camden, surgeon, born in South Carolina in 1822; died in Santa Fe, New Mexico, 3 September 1872. He was educated in his native state, and graduated in medicine at the University of Pennsylvania in 1836. He entered the U. S. army as assistant surgeon on 21 August 1838, served in the Seminole war, and was then stationed for several years on the western frontier. At the beginning of the Mexican war he went with General Taylor to the Rio Grande, was present at most of the battles in the campaign toward Mexico, and entered that City when it surrendered. For these services, as well as for gallantry in action, where he several times took the place of commanding officers who had been killed or wounded, Dr. De Leon twice received the thanks of congress, but was again assigned to frontier duty in Mexico, on the ground of his great energy and hardihood. He was promoted to surgeon, with the rank of major, on 29 August 1856, and on 19 February 1861, resigned his commission and was placed at the head of the medical department of the Confederate army. At the close of the war he went to Mexico, but after a year's residence in that country he returned to New Mexico, where he had been stationed for many years, and owned property, continuing in practice until his death. He was a man of fine literary, culture, and a vigorous writer.
