Gerald Rehkugler, a faculty member since 1958 and Professor Emeritus of Biological and Environmental Engineering, developed a rollover-protection system for tractors that have become a standard feature to all tractors. He is also actively involved in a movement to preserve and display the University’s collection of antique plow models.
