Vaclav E. Bexes, A.B., Harvard College, 1950; M.A. Ph.D., Prince- 

 ton University, 1953. Instructor in logic and philosophy of science, 

 Princeton University, 1952-53; Bell Telephone Laboratories, 1953-. 

 Since joining the Laboratories, Mr. Benes has been engaged in mathe- 

 matical systems research, involving stochastic processes describing the 

 passage of traffic through a switching system. He is the author of a 

 number of papers on mathematical logic and analytic philosophy. 

 Member of the Mind Association, the Association for Symbolic Logic, 

 the Listitute of Mathematical Statistics, American Mathematical 

 Society, and Phi Beta Kappa. 



E. X. Gilbert, B.S., Queens College, 1942; Ph.D., Massachusetts 

 Institute of Technology, 1948; Mr. Gilbert's early employment was with 

 the M.I.T. Radiation Laboratory. He joined Bell Telephone Labora- 

 tories in 1948. His work has been on studies of the information theory 

 and on the switching theory. He now is part of the communication 

 fundamentals group. Mr. Gilbert is a member of the American Mathe- 

 matical Society. 



H. 0. PoLLAK, B.A., Yale University, 1947; M.A., Harvard Univer- 

 sity, 1948; Ph.D., Harvard University, 1951; Bell Telephone Labora- 

 tories, 1951-. Mr. Pollak has been engaged in mathematical research 

 and mihtary systems analysis. He is a member of Phi Beta Kappa, Sigma 

 Xi, American Mathematical Society and Mathematical Association of 

 America. 



M. B. Prince, A.B., Temple University, 1947; Ph.D., Massachusetts 

 Institute of Technolog}^, 1951; Bell Telephone Laboratories, 1951-1956; 

 Hoffman Semiconductor Division of Hoffman Electronics Corporation, 

 1956-. Between 1949-51 he was a research assistant at the Research 

 Laboratories of Electronics at M.I.T. Avhere he was concerned with 

 cryogenic research. At Bell Telephone Laboratories, Mr. Prince was 

 concerned with the physical properties of semiconductors and semicon- 

 ductor devices and was associated with the development of silicon de- 

 vices, including the Bell Solar Battery and the silicon power rectifier.
