That is sad indeed. I was fortunate enough to have attended the very first Advent Videobeam school way back in the 70's. In fact I want to say it was in 1974 that it was held. We were given a complete tour of the factories at the time and it was quite impressive to say the least. Even though not capable of a really bright image the original Videobeams were quite sophisticated televisions thanks to Henry's inginuity. He will be sorely missed in the industry.
