At war’s end, Guennel remained in Germany to interrogate suspected war criminals in advance of the Nuremberg War-Crimes Tribunal. He grilled arrogant generals and haughty industrialists and even the mistresses of Nazi bigwigs. Of Hedwig Potthast, Heinrich Himmler’s mistress, Joe said, “I found her unremarkable in every way.”
After the war, he returned to the U.S. and earned his doctorate at Indiana University in the field of Palynology—the study of ancient plants—that earned him a career with an oil company in Colorado to help it find places in the western United States where oil deposits were likely to be. But it was his love of soccer—the game he played as a young boy in Germany—that was his true passion. Starting the first soccer team at Indiana University, Joe went on to create soccer programs everywhere he went, especially in his new home state of Colorado.
Immersing himself in every facet of the game—from player to coach to referee to publicist to administrator—Joe helped the once-foreign sport grow into an all-American one that became one of the fastest-growing sports in the U.S. As a result of his untiring efforts to turn soccer into a mainstream American game, Joe was inducted into the United States National Soccer Hall of Fame in 1980. His 50-year-long friendship with Flint Whitlock, also an acknowledged “soccer nut,” resulted in the collaboration that produced this book.
