The Germantown Bank was built in 1922 and established by Augustus R. Selby, part-owner and manager of the Liberty Milling Company, and Andrew H. Baker, a local entrepreneur and head of the A. H. Baker Insurance Company of Washington. Selby was also vice-president of the First National Bank of Gaithersburg, chairman of the Board of Citizens Building and Loan Association, and in 1948 was elected to the first Montgomery County Council when the county adopted the charter form of government. Selby and Baker each owned residences across Rt. 118 from the bank in Germantown, and both houses were destroyed by fire in the late 1970's. The bank was created for the convenience of Germantown residents and mill workers. Augustus Selby served as its president until 1958, when it merged with 1st National Bank of Gaithersburg and was chartered as Maryland State Bank of Montgomery County. For many years, Mrs. Carrie Greene, sister of Carlton Browning, the local postman, managed the bank. On October 30, 1960, it merged with Suburban Trust, later Suburban Bank, and in 1966 Lewis Wood came to manage it. In the spring of 1983, Suburban Bank moved to a new building at the corner of Germantown Road and Middlebrook Road, and two years later merged with Sovran Bank. The old bank building was then given to the county and used for a time as a waiting room for the commuter train. The building is constructed of brick painted white, with barred windows and door and an entrance flanked by columns, giving an impression of solidity and compactness typical of small-town bank buildings of its time.
