History Shelbyville is the home of Josephine Garis Cochran who invented one of the first mechanical dishwashers ever built in 1886. It was exhibited at the 1893 Chicago Columbian Exposition, where it won "the highest award." Another Shelbyville invention, the first commercial pick-up baler, was designed and developed by Raymore McDonald, as conceived and financed by Horace M. Tallman and his two sons, Leslie and Gentry. These balers were marketed for many years by the Ann Arbor Machine Company of Shelbyville. This concept of field processing of farm forages made a significant contribution to the efficiency and economy of harvesting in the world's agriculture. This basic field pick-up mechanism has been used in over 15 million balers. The American Society of Agricultural and Biological Engineers designated Shelbyville as an historical landmark of agricultural engineering, of which there are only 47 in the entire United States. Mr. Tallman's home has been restored and is on the National Register of Historic Places. Located on West Main Street, the Tallman home is currently part of the Shelby Inn.
