Winston E. Kock, B.E., University of Cincinnati, 1932; M.S., 1933; 

 Ph.D., University of Berlin, 1934. Institute for Advanced Study, Prince- 

 ton, New Jersey, 1935-36. Director of Electronic Research, Baldwin Piano 

 Company, Cincinnati, Ohio, 1936-42. Bell Telephone Laboratories, Re- 

 search Department, 1942-. Dr. Kock was engaged in radar antenna work 

 in the Radio Research Department during the war. He is now engaged in 

 microwave and acoustic research. 



W. D. Lewis, A.B. in Communication Engineering, Harvard College, 

 1935; Rhodes Scholar, Wadham College, Oxford; B.A. in Mathematics, 

 Oxford, 1938; Ph.D. in Physics, Harvard, 1941. Bell Telephone Labora- 

 tories, Inc., 1941-. Dr. Lewis was engaged in radar antenna work in the 

 Radio Research Department during the war; he is now engaged in micro- 

 wave repeater systems research. 



L. A. Meacham, B.S. in Electrical Engineering, University of Washing- 

 ton, 1929; Certificate of Research, Cambridge University, England, 1930. 

 Bell Telephone Laboratories, 1930-. From 1930 to 1941 Mr. Meacham's 

 work dealt with crystal oscillators, multivibrators, phase shifters, and other 

 devices used in precision standards of frequency. During the war he devel- 

 oped range measuring devices for radar, and has since been concerned with 

 applications of pulse techniques to multiplex telephony.
