Jacob Erdman, a junior studying German and political science, poses for a portrait in Folwell Hall on Tuesday, April 30. In March, Erdman saved a man's life on campus. He was on his way home from class and stopped in Nicholson Hall to turn his music on when he noticed a group of people surrounding a man, Mike Vaughan, who was going into cardiac arrest. Erdman checked for a pulse, then located the nearest AED and administered CPR to Vaughan until paramedics arrived. Vaughan lived for two more weeks.
