[2] Frank Zummach enrolled at the Marquette University Law School in 1933 after finishing his undergraduate studies the year before.

[4] After the season, Zummach stepped down as coach "because of a dispute with business manager Carl Roth over Roth's insistence on paying rookie Kenny Buehler a greater salary than veterans Eddie Dancker, Rube Lautenschlager and Kenny Suesens," according to The Oregonian sports writer Brian Gaynor.

[3] He stayed active in the Wisconsin Bar Association, the St. Clement Catholic Parish, the Knights of Columbus, and also raised a family with his high school sweetheart.
