--f403045c0d7c4d2f6b05658b8791 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable I asked Leland Jackson; he says "Yes, Roberts et al did great work at Colorado, but were initially better known in the controls community. I knew Dick Roberts best and was greatly saddened when he died at a young age." Looks like he died in 1990, according to his 1992 book: https://books.google.com/books?id=3DhSDvAAAAMAAJ&q=3D% 22richard+a+roberts%22&dq=3D%22richard+a+roberts%22&hl=3Den& sa=3DX&ved=3D0ahUKEwigpZD-r7HZAhWGx4MKHU7sD8wQ6AEIOTAD His "book on Signal Detectability in 1965" was his dissertation at University of Michigan. And Robert A. Gabel went from Colorado to MIT Lincoln Laboratory, where he was for 25 years by 2009, says here: http://news.mit.edu/2009/qcc-0527 Dick On Thu, Feb 15, 2018 at 8:06 AM, Richard F.
