Horn was born in Philadelphia, in 1840, and lived there nearly all his life. He was the oldest child of Philip Henry Horn and Frances Isabella Brock and the grandson of Philip Horn, born in Rhenish Prussia, who came to America in 1798.
He graduated from the Philadelphia High School and received his doctorate in medicine from the University of Pennsylvania in 1861.
In 1862 he went to California. In 1863 he became assistant surgeon in an infantry regiment of California volunteers, becoming surgeon in 1864. Mustered out with the staff of his regiment in April 1866, he returned to Philadelphia and began the practice of medicine, which he continued for the rest of his life, specializing in obstetrics. During his army service in the West and Southwest he had collected Coleoptera extensively. He had been attracted to this group of insects at an earlier date, and his first paper was published in Volume XII (1861) of the Proceedings of the Academy of Natural Sciences of Philadelphia.
From the time of his return to Philadelphia he was constantly engaged, aside from his medical practice, in the study of Coleoptera. He was associated in his earlier work with Dr. John L. LeConte, and the great work, The Classification of the Coleoptera of North America, was published by the Smithsonian Institution (Miscellaneous Collections, vol. XXVI) in 1883 under their joint authorship. He had been greatly interested in the Academy of Natural Sciences from his earlier days, and after the death of LeConte in 1883 he was elected his successor as director of the entomological section of the Academy, holding this office until his death. He was made professor of entomology in the University of Pennsylvania in 1889, but the position was purely honorary, unconnected with teaching or lecturing. He died at Beesley's Point, N. J. , in his fifty-eighth year.
