Harry Lucas Tillson, who for a number of years has been engaged in the electrical supply business in Boone and who is an electrical contractor, is a native son of this city, where he was born February 22, 1883. He is a son of Josiah P. and Olive ( Lucas ) Tillson, the former born in Otsego, New York. Their son, Harry L., attended the schools of Boone until 1899, spending the last three years in high school under the direction of Professor George L Miller. He subsequently entered the Iowa State College at Ames, where he took a course in electrical engineering, graduating with the class of 1903. He then returned to Boone, where he remained until his removal to the Kansas oil fields, where he was professionally employed for a year and a half. He next became a member of the staff of the Boone Electric Company, continuing with this concern for one and a half years. At the end of that time he established himself independently as an electrical contractor and also as a dealer in electrical supplies.
On July 10, 1905'; Mr. Tillson married Miss Alice Nelson of Boone, a daughter of George C. and Adelia (Hibbard) Nelson.
