One of our most prestigious members has passed away. Georges Guiochon, a previous WCDG President, after defeating pneumonia finally succumbed to neuromuscular failure due to Post Polio Syndrome on October 21, 2014. He was 83 years old and still working at UT Knoxville until the day before he entered intensive care on October 7.
Arrangements are underway for Memorials to be held in Paris, Buffalo, and UT Knoxville.
With warmest regards from another previous WCDG President, Lois Ann Beaver, surviving spouse of Georges Guiochon.
