Bp Henni had a real problem beyond what you mentioned. “Retaining the culture” of the Germans and Poles inevitably meant retaining a culture which was far more Socialist than perhaps he wanted. The Guilds were influential overseas, and Milwaukee became a Union Town, encompassing a very large Catholic labor population.

Ultimately this was almost a disaster, as the Communist infiltration of the CIO/UAW led to sabotage at the Allis-Chalmers plant (which was making war materiel.)

Ultimately, (IIRC) George Meany cleaned out the CIO and merged it into the AFL. Meany was a very Catholic guy…

The German influence also had its effect on the liturgy in Milwaukee. Henni imported a fellow named Singenberger (via Cincinnatti) to Milwaukee. Singenberger’s training was taken in Regensburg under the influence of the Liturgy Reform movement. As a result, Milwaukee was quite ‘progressive’ liturgically (but always within the guidelines of Rome.) Milwaukee was one of the few Dioceses which allowed and encouraged the “Dialog Mass,” really the pre-cursor of the Pauline Rite in many ways.

Of course, Jos. Ratzinger was ALSO a Regensburg guy…
