Plans for a new community close to St. Louis were begun after the St. Louis fire of 1849 and the preceding and subsequent cholera outbreaks that killed one-tenth of the residents of downtown St. Louis. In 1850, Hiram W. Leffingwell and Richard Smith Elliott bought land from downtown, which was at about the same time James P. Kirkwood, chief engineer of the Missouri Pacific Railroad, was laying out a route for the train line. The city of Kirkwood, named after the chief engineer, was platted in 1852. Kirkwood was the first suburban municipality built outside of the St. Louis city boundaries.
