FYI -- Bob Fano was my undergraduate advisor; his lovely daughter, Paola, worked at BBN for a while. It's bizarre that the NYTimes makes such a big deal out of CTSS; I consider Fano's work in information & coding theory (& whatever he did during WWII, much of which may still be classified) his major accomplishments. He was also an incredibly good teacher, and a wonderful advisor: he finally convinced me that Kronecker may have been somewhat short-sighted ("God created the integers..."), and got me to take probability. http://www.nytimes.com/2016/07/27/technology/robert-fano-98-dies-engineer-wh...
