Stepladders were invented by little known Daytonian John H. Balsey. A carpenter by trade, Balsey devised a wooden stepladder in 1865 in his shop on East First Street. The wonderfully logical invention was portable, suitable for any use and was patented on Feb. 8, 1870. Balsey later was granted patents in 1875 for an adjustable table leg and in 1876 for a paper bag machine, but throughout the 1870′s he concentrated on the manufacture and sale of the creation which earned him fame as “The Stepladder King.”
