For several weeks I've been unable to reach Mike Stewart (of Lebanon, Ohio) who, though we've only rarely met in person, has been a best friend for me and for Rachi. A master programmer, he really was a substantial help in developing Rachi's voice output and computer control system and helped me over the rough spots as I designed the CANbus/Roboteq wheelchair control system. Eventually I contacted the the Warren County, OH sheriff's office and after checking utility and post office records and contacting Mike's neighbors they broke into his home and found that he had died.
In Judaism, we say "may his memory be a blessing" and indeed that's the case. This is a personal loss for us, but also a loss for anyone with a disability as he was an astounding example of generosity and clear and practical thinking.
May his memory be a blessing.
