Robert F. Christy - R.I.P.

Robert F. Christy, one of the last remaining "big names" on the Manhattan Project, has passed away at the age of 96.  There are just eleven or so of the old guard left.  In Oak Ridge, Tennessee, photographer Ed Westcott is still around.  Christy had a falling out with Edward Teller in the 1950s after Teller's testimony was instrumental in getting Robert Oppenheimer's security clearance pulled.
