The old courthouse, designed by famed Kansas architect George Washburn, was in operation from 1891-1952. A cornerstone from the courthouse is part of the Johnson County Square. The first meeting of Johnson County, as an organized local government initially led by an appointed “county tribunal,” is celebrating its 166th anniversary on Thursday, Sept. 7. Members of the tribunal were John T. Ector, John Evans and William Fisher Jr. They were appointed by Kansas Territorial Gov. Robert J. Walker. Dr. John T. Barton (founder of Olathe) was appointed county treasurer.
