The DeForest Moravian Church was founded as a home-mission congregation on April 13, 1885 in the small, agricultural prairie township of Windsor, Wisconsin. Beginning in early 1876, worship services were held in the homes of Ernest and Fred Karow under the guidance of Brother W. Stengel, who was then pastor of the Mamre Moravian Church, about thirty-five miles away. When other families in the immediate area took interest and began attending these services, it was decided to hold the Sunday meetings in a small rural schoolhouse. 

In June 1883 Reverend J.G. Kaltenbrunn, a retired pastor, arrived and served them earnestly for almost nine years. The “little group on the prairie” increased in numbers and at the annual church council meeting in January 1885, it was decided, after many prayers, to build their first church building. After considerable discussion, the site for the new structure was chosen – a one-acre lot located two andone-half miles east of the village of DeForest. The small white church was completed using the resources of its members and friends at a mere cost of twelve hundred dollars.
