I missed that Merrill Skolnik passed away. Not audio-related, but a giant in the RADAR world. Back in the early 1990's I was presenting on a research contract I had with NRL and he sat in. I wasn't sure who he was until one of the program managers said "He wrote the book!" when we clarifying a few things. I don't recall that he said much, but did come up to talk afterwards. He was a great guy and very sharp despite being a self-described "bureaucrat". I still have his book on my shelf at home.
