David B. Moore, M. D., a prominent physician of Osage City and one of the medical examiners of the pension board, was born in St. Joseph county, Michigan,, Sept. 9, 1841, son of Henry R. and Lydia (Burron) Moore. His grandfather was a Pennsylvanian who served in the war of 1812 and took part in the battle of New Orleans. He was a Republican and had the honor to vote for John C. Fremont, the first Republican nominee for president. James Moore moved to Ohio, later to the State of Michigan and, in 1850, to Iowa, where he died, at the age of ninety-six. Henry R. Moore, father of D. B. Moore, was born in Lancaster county, Pennsylvania, and accompanied his parents to Ohio when a boy. He received the education afforded by the pioneer schools of that day and read law with Judge Cowen, was admitted to the bar and practiced for a while in Ohio, but abandoned it to engage in mercantile pursuits. He moved to Michigan and remained in business there until 1850, when he removed to Louisa county, Iowa, and remained in business there until his death, in 1855. Dr. Moore's maternal grandfather was born in Virginia; he moved to Michigan at an early day and lived in that state until his death at a very advanced age.

Dr. Moore received his elementary education in the public schools and then entered the Presbyterian College at Washington, Iowa, graduating in 1860. He began to study medicine, but at the first call for volunteers, at the outbreak of the Civil war, enlisted in the Union army. He served in the West under John C. Fremont and Generals Schofield and Logan. In 1863 he was discharged on account of ill health. While in the army Dr. Moore took part in many of the severest battles fought in the West. At the close of the war he came to Kansas and settled on a piece of land near Quenemo, remaining there until 1871, when he moved to Cloud county. There he engaged in the practice of medicine until 1895, when he located at Osage City. Dr. Moore has built up a large practice; he was appointed a member of the medical examiners of the pension board, in 1902, and in 1909 was appointed health officer, both of which positions he still holds. He is a member of the Kansas State and American Medical societies; is a member of the Masonic order, being past master of Signal Lodge, No. 151, Osage City, Kan.

In 1863 Dr. Moore married Emaline Little of Iowa. Her maternal grandfather, Benjamin Britt, served with distinction in the war of 1812 and was buried with military honors. Two daughters have been born to this union: Mary is the wife of Dr. S. S. Pigman of Concordia, and Irene M., is the wife of Charles E. Abell. The family are members of the Presbyterian church.
