The M.P. Moller organ at First Baptist Church was installed between 1956 and 1957 when the church sanctuary was constructed. (The sanctuary was built on the same site as the 1897 sanctuary that was removed.) When installed, the organ was described in this manner:

Our lovely new Moller Organ will consist of three manuals and pedal keyboard. As originally installed it will cost $25,000.00. It will have nineteen stops with draw knob console and will have 1,381 separate pipes. The console will be designed for eight more stops.

The additional stops were added in 1964 at a cost of $8,250.00. It was later discovered that in this process some of the original pipes were removed and found by technicians in a St. Louis church…these were replaced by the Moller representative, W. A. Brummer, out of Granite City, Illinois. In 1997 the organ console was renovated; re-stained and given electronic components. Between 2007 and 2009 the entire organ was re-leathered at a cost almost twice as much as its initial construction price.

This grand instrument has been utilized in nearly 3,000 services of worship! First Baptist is also blessed to have had Colleen Ostercamp as organist since 1992.
