I had the pleasure of working with Barry and Patty at IBM creatiing software with IBM and operation support in the Sunnyvale 'blue cube' with the orbit analysis group. He was the resident expert in the orbit analysis group since he was involved in writing the software with Patty. He excelled in anything he tackled: bowling, golfing and solving very difficult orbit analysis problems that occurred. He loved the friday night poker games with all his friends in the OA groupl He is one of the 'best' and he will be missed.
