The following information was provided by Thomas Starck:

It is with sadness that I inform the class of '64 of the passing of Greg French.  Greg suffered a heart attack while returning from a cruise with his wife, Dottie, last Sunday evening. Greg and I grew up a block apart and shared many adventures and misdeeds.  We also both served in the Navy and overlapped our time spent in Hawaii stationed on different ships. Greg intrduced me to my wife, Claudia, and served as my best man at our wedding.

Rest in peace my friend!
