Slightly off topic --
We recently released a video interview with Clive Finkelstein, the father of information engineering. In the first 35 seconds, there is a tribute to 16 pioneers in our field.
When we released the video recently, I asked several industry veterans how many of the 16 they recognized. Peter was the only person who replied he recognized all 16.
