Founded In 1937 by 21-year-old Gerhard Schroth, the choir was originally known as the Walther League A Cappella Choir. It was a choir for Lutheran young people in their teens and twenties. It soon built a solid reputation and, in the 1940s, performed Brahms' A German Requiem with Dr. Frederick Stock and the Chicago Symphony Orchestra at Orchestra Hall.

Over the years, the choir has specialized in performing the finest sacred a cappella works of the great choral masters, as well as modern composers. In addition, the choir has sung major choral works such as Bach's St. John Passion and B Minor Mass, Mozart's Requiem Mass and Great Mass in C Minor, Haydn's Lord Nelson Mass and The Creation, and Brahms' A German Requiem. The choir has sung in all of the major venues in Milwaukee as well as dozens of local churches.

A variety of recordings and appearances on Milwaukee television and radio, as well as concert tours to Chicago, St. Louis, Fort Wayne, Madison, and throughout Wisconsin, have helped build the choir's reputation as one of the foremost Christian choral groups in the nation.
