A native of Glendale, CA, Koehnle graduated with a Degree in Philosophy and was a member of the Thomists and Block Clubs.
Boxing, too, proved a popular sport with Gene Fisher, Jack Taheny, Gerry  O'Connor, Don Beechinor, Jim Walsh, Ralph Icaza, and heavyweight John Koehnle proving to be the team mainstays.
WHAT HAPPENED TO BOXING? At this time last year, the boxing program was in full swing and weekly shows were the rule on the campus. But comes 1943 and what have we? Not even remnants of the pugilistic art are left. And this at a time when all the United Armed Forces are practically begging the colleges to install boxing facilities as part of their war-training program. USF has long led the way in this phase of college sports, producing more outstanding professionals than any school in the Bay Area. Chief among these is Earl Booker who may be the next 135 pound World's champion. Booker took the Pacific Intercollegiate title in 1935 and 1936. He is only one of the 13 men who have worn crowns for the Dons in the 10 years the tourney has existed. Some others include Pete Breceda, Gene Cervelli, Jim Mace, Brad Buckner, Jim Rice, "Doc" Flynn, and Norbert Meehan. Most have had a fling as professionals. With the war-effort depending so much on contact sports, it is time something be done about boxing. Around the campus we have several good prospects and former prep ring men. We also have some of last year's boxing men, namely John Koehnle, Gerry O'Connor, Jack Taheny and Bill Bussenius. They could lend a helping hand to the regeneration of the sport to its proper level on the college curriculum (TheFoghorn).
