Percy Daniels (September 17, 1840 in Globe Village in Woonsocket, Rhode Island – February 14, 1916 in Girard, Kansas) was an American soldier, businessman, civil engineer, surveyor, author and Populist politician.
Daniels was the second son of Judge David Daniels (1804-1847), a Rhode Island lawyer and businessman who acquired his title by serving as a Judge of the Common Pleas court for a term. Daniels' mother was Nancy Ballou, daughter of Dexter Ballou, a wealthy Rhode Island mill-owner. Daniels' father and mother both died when he was six years old. He received a good education, studying at Westminster Seminary in Westminster, Vermont and the University Grammar School in Providence, Rhode Island. His studies in civil engineering were interrupted by a serious illness. At the outbreak of the Civil War Daniels was not healthy enough to enlist, but after spending time in Michigan recovering his health he enlisted in the 7th Rhode Island Infantry in May 1862. By January 1863 he was in command of Company E, which he had largely raised himself, and he was made a captain in March 1863. His older brother Herbert (1836-1926) helped him recruit and served in the same regiment. In June 1864 Percy was raised to lieutenant colonel and breveted to colonel, as Col. Zenas Bliss had been injured; Daniels remained in command of the regiment for the remainder of the war.
After the Civil War Daniels spent several years doing civil engineering work for the Cincinnati Southern Railway. He then travelled around the Midwest and decided to settle in Kansas. After a trip back to the east coast to marry schoolteacher Eliza Eddy in June 1867, he settled in Crawfordsville, Kansas and opened a store with his brother-in-law William Eddy. He also acquired land in Crawford Township near Girard which he named "Narragansett Farm" in memory of his native Rhode Island. After a while he gave up the store (Crawfordsville was rapidly disappearing anyway) and worked as a farmer and surveyor. In 1873 he went back east to work in the engineering department of the city of Worcester, Massachusetts, becoming chief engineer by 1878 when he resigned and returned to Rhode Island, where he did engineering work and helped resolve the estate of his brother Francis A. Daniels. In 1881 he returned to Kansas, where he principally worked on his farm, although he spent periods of time doing engineering work for railroads and serving as the county surveyor in Crawford County.
