Alfred “Fredy” Willommet had a brief amateur boxing career in the late 1940s and early 1950s. He won the featherweight competition at the Bernese Oberland Championships in January 1952, then eventually went to capture the Swiss featherweight title a few months later at a meet in Biel/Bienne. Selected for the Olympic team after successfully participating in a pre-Olympic tournament, Willommet competed in the featherweight tournament in Helsinki, losing to Seo Byeong-Ran of South Korea by a 3-0 decision in his sole match. Willommet was from the canton of Vaud, and resided in Vevey, Payerne and Lausanne at different points in time. He retired from competition shortly after the Olympics, and was coaching boxing in Lausanne by May 1954.
