Eugene R. "Bumper" Tormohlen (May 12, 1937 – December 27, 2018) was an American professional basketball player and coach.

During his time in Knoxville, Bumper became a 3-year starter, set the Tennessee career rebounding record (1,113 rebounds), a 16.9 rpg rate; was twice named All-SEC and was named to Converse's All-American team and become known to scores of Vols fans as the "Chairman of the Boards."

After a splendid college career at the University of Tennessee, Tormohlen was selected with the fifth pick in the second round of the 1959 NBA draft by the Syracuse Nationals.

However, his first years as a pro were spent in the NIBL with the Cleveland Pipers before being traded to the Kansas City Steers in the fledgling American Basketball League.

With the Hawks at 28–46 and mired in a ten-game losing streak, he was promoted to replace Cotton Fitzsimmons on an interim basis on March 30, 1976.
