On May 15, 1875 a letter was sent to residents of Red Bud announcing that a "limited partnership" bank "The Red Bud Savings Bank of Ohlwine, Schrieber, & Company", had been established by a group of businessmen of the community. The names of the original partners were as follows: David Ohlwine, Charles Schrieber, Herman Schrieber, William Schuck, A.L. Wilson,

William Guebert, Christian Guebert, Gotlieb Buch, Fred Stellhorn, Henry Ratz, Herman Nagel, William Schroeder and Diedrich Liefer.

The bank began business on June 1, 1875 with $10,000 in assets. David Ohlwine served as the bank's first president, Charles Schrieber, Vice-President and A.L. Wilson, Cashier. George Parrott made the first deposit on June 7, 1875, for $1,000. By the end 1875, the bank had assets of $19,423.21. In 1895, a re-organization took place. After Charles Schrieber's death, David Ohlwine resigned, and his son Walter succeeded him as president. Herman Schrieber succeeded his father as vice president and Henry C. Wahlmann became Cashier. Walter Ohlwine died in 1924 and Herman Schrieber followed him as president until he died in 1929. Albert Schrieber followed Herman in office as president until 1964. Adrian Rathert who had served as vice president and cashier for 44 years was then elected president. Through the years many prominent citizens of this area have served as directors of the bank. Many of the surnames of the original founders are represented on the board of directors today. The family name "Schrieber" has always been represented upon our Board of Directors.

On June 10, 1919, the partners of the Red Bud Bank of Ohlwine, Schrieber & Co. met in a regular annual session and unanimously approved the authorization of the incorporation of the bank as the First State Bank of Red Bud.

First State Bank of Red Bud became a member of the Federal Reserve Bank of St. Louis in March of 1939, chartered as a state bank.

In 1985 Red Bud Bancorp, Inc. was formed as the holding company for First State Bank of Red Bud and stock was re-issued under the name of the holding company.

Throughout the years of service the bank has always been located on the first block of the northwest corner of the town square in Red Bud. In 1920, First State Bank of Red Bud moved from its first banking house just east to a new building. The original banking house was eventually torn down to make room for the drive-up window. The new building housed the Schrieber Store among other businesses. This building was remodeled and enlarged in 1963. In 1987, this building was torn down and replaced with a more modern structure, the current bank building.
