Dean, along with Russ Wurster ‘57 dedicated the Neil A. Armstrong Library in 2018 at the Founder’s Day Dinner and later celebrated for several hours at Harry’s after dinner.
Last November, he got together with his fraternity brothers to donate more items and historical newspapers to the library. He especially wanted to present the “World Championship of Farting” record album to Russ Wurster at the dinner. His brother Neil had won the album/trophy on the aircraft carrier “Essex” on his way home from the Korean War. It is now on display in the Armstrong Library.
