IMMANUEL CONGREGATIONAL UNITED CHURCH OF CHRIST
In 1867 Rev. Jesse Guernsey, superintendent of Iowa Congregationalism, directed the construction of a white frame church on the hillside above the fire station at 18th Street and Central. This building would serve the congregation for twenty years and become known as the German Congregational Church.
The first permanent pastor inherited a congregation of five adults and two children, an unfinished building, and a debt of $1,200. Under the leadership of Rev. Ficke, the problems were gradually settled. Construction of the present church at 18th and Jackson STREETS was begun with the laying of the cornerstone on October 16, 1887. The original church was rented to other church groups for several years and then torn down in the 1890s, and a parsonage was constructed on the site. Ficke continued in his position until his death in 1911.
The years during WORLD WAR I were difficult for the German-speaking congregation when anti-German sentiment in the community was high. The first separate English services were held during the pastorate of Reverend Gustav B. Bauman (1921--1927).
