His obituary or wikipedia page are well worth a read for what he was involved in - though he probably is best known for lighting a BBQ in under 5 seconds by use of liquid oxygen, and getting into trouble with the local firedepartment for that.

He used to have that video on his website - which I've discovered via a Usenet discussion not too long after it happened. It was one of the first videos I've downloaded via a web browser, and almost certainly the first video made with a digital camera I've ever seen.

George was really into video stuff - he had stacks of 8mm video tapes in his office, and of course stacks of exabyte drives. He had many different cameras and was always trying new ones out. He was also a really early adopter of laserdiscs, and I have a few discs he gave me when I graduated.
