San Francisco Chronicle of August 19, 2004:
DE GROOT, Marc - In Taos, NM, August 8, 2004. Age 45. Beloved son of Barbara and Louis de
Groot; brother of David de Groot. Nephew, cousin and friend to many. Born in Brooklyn, NY on July
2, 1959, and grew up in Dutchess and Rockland Counties NY and Paris, France. Settled in the Bay
Area in 1978. A too tender-hearted soul, mostly self educated, with a brilliant and inquisitive mind
who was a mathematical wizard and pioneer in the use of Virtual Reality Modeling Language.
Founder of Immersive Systems, Inc. Created Meme, a development system for virtual world
software. He contributed to, without remuneration, the technology which had a huge impact on
disabled children - that enabled them to move around in his virtual world using only their facial
muscles or other input, and thereby broadened their horizons. Within minutes of the 1989 Loma
Prieta earthquake he was at the disposal of SF General Hospital with his mobile amateur radio
station to ensure their communications capability. Services were held at Rolling Hills Memorial Park,
Richmond, CA. Donations to the Marc de Groot Mental Health Fund, c/o Oakland Jewish
Philanthropical Foundation, 1850 Mount Diablo Boulevard, Suite 370, Walnut Creek, CA 94596-4423.
