* Does anybody know where to find a photograph of any of
   the following  logicians?
 
        Jean Nicod
(he was the first person to find a
                  single axiom for any sentential calculus)
          David Meredith
(the first person to program
                 a computer to search for proofs using the
                 rule of condensed detachment--it was
                 UNIVAC, no less)
        C(arew) A(rthur) Meredith
(the all-time grand
                 master of this sort of thing)
