John (Jack) Wilhelm died suddenly due to complications from routine heart surgery on April 21, 2009. Jack took early retirement in 2003. At that time, he and his wife Diane sold their Naperville, IL house and became full time RVers.  During the past 6 years, they were able to daily experience the beauty and wonders of our country.  Jack also had plenty of time to study and improve his chess game, participate in many postal chess tournaments, and play in tournaments throughout the West and Midwest.

John (Jack) Wilhelm - May you rest in peace.
