I didn't really know Ken, but I attended some conference calls with him in a larger group. His expert knowledge and clear communication in a field (traceability codes) most of us were unfamiliar with was outstanding and memorable. I just learned of Ken's passing and that our project will thus no longer have his guiding influence. He will be sorely missed on our project and I'm certain also by those who loved him. My condolences on the loss of this dedicated man.
