Karl Von Tagen helped give Idaho its first two Big Sky Conference titles in swimming with a pair of impressive performances. Von Tagen was the top freestyle swimmer for the Vandals in 1964 and 1965 with three Big Sky Conference titles and records each season. In 1964, he led the Vandal men to their first swimming title with championship efforts in the 50 and 100 meters and 200-meter freestyle. At the meet, he broke both the Idaho school and the Big Sky Conference records in all three events and qualified for the NCAA Championships in the 50m and 100m. A year later, he gave a repeat performance for the Vandals, as he swept the 50m, 100m and 200m yet again with new records in each one. He added another title as the fourth leg of the Idaho 400m freestyle relay team to lead the Vandal men to their second Big Sky swimming title in as many seasons. For the second year in a row, he qualified for the 50m and 100m freestyle events at the NCAA Championships. In his final action for the Vandals, he took 12th in the 50m free in school-record time of 21.8 at the meet.
