Bill "Ches" Cheswick
Bill Cheswick logged into his first computer in 1968. He has been programming and working for (and against) computer security ever since. He joined ARPAnet and then Bell Labs in the 1980s. He co-created and patented the first DNS proxy and co-authored Firewalls and Internet Security: Repelling the Wily Hacker. Along with Hal Burch, he worked on corporate and Internet mapping that still appear in publications and talks today. He has earned more than a dozen patents in visualization and authentication. Ches "retired" in 2012: it is not likely to last. He is a Visiting Scholar at the University of Pennsylvania where he hangs out and occasionally teaches classes. He is now an enthusiastic, dedicated, and inspiring mentor!
