Tragic Collision Claims Life of USD History Professor and Renowned Scholar, Clayton Lehmann

On November 14, a fatal collision between a car and a bicycle occurred at the intersection of East Main Street and Anderson Street in Vermillion.

The bicyclist, identified as Clayton Lehmann, a 67-year-old professor at the University of South Dakota, suffered injuries and succumbed to them two days later in a Sioux Falls hospital.

The car’s driver, a juvenile, remains unnamed due to their age, and the Vermillion Police Department is actively investigating the incident.

Lehmann, a respected figure in the academic community, had dedicated 35 years to teaching Greek and Roman history at USD.

A Celebration of Life is scheduled at the USD Vermillion campus to honor his legacy.
