The Radka–Bradley House also known as the Bradley House, was built as a private house at 176 West Michigan Avenue in Rogers City, Michigan. It was listed on the National Register of Historic Places in 1991, and is now the Presque Isle County Historical Museum.HistoryThis house was constructed in 1914 by George J. Radka, a local contractor and the owner of a planing mill. Radka died unexpectedly at the end of 1914, and in 1915 the house was sold to J. L. Marsters, general superintendent of the Michigan Limestone and Chemical Company. Later that year, Marsters sold the house to his boss, Carl D. Bradley, a shipping magnate and president of Michigan Limestone and Chemical.Bradley made extensive revisions to the home, enlarging it considerably. While living there, he launched Michigan Limestone and Chemical Company from a small-scale quarry into a national producer of limestone. Bradley was also heavily involved in the business and social life of Rogers City, serving on the boards of the Presque Isle County Savings Bank and of Rogers City Light and Power, helping found the Westminster Presbyterian Church, and serving on the School Board. Bradley lived in the house until 1928, when he died unexpectedly during a vacation to Pasadena, California.After Bradley's death and in accordance with his contract, Michigan Limestone purchased the house from his widow. Bradley's successor as president, John G. Munson, lived there from 1928 to 1939. When Munson moved along to a higher position in U.S. Steel, Michigan limestone's parent company, the house passed to his successor Irvin L. Clymer, who lived here until 1950. When Clymer was likewise promoted, U.S. Steel's northern district manager Joseph Valentin occupied the house until his retirement in 1957.
