conductor devices including point-contact transistor development, 

 transistor reliability studies and the development of low-noise alloy- 

 transistors. He also served as instructor of semiconductor electronics in 

 the Laboratories Communications Development Training program. At 

 present he is engaged in surface studies and semiconductor device re- 

 liability. Member of Sigma Pi Sigma and Sigma Xi. 



David C. Hogg, B.SC, University of Western Ontario, 1949; M.Sc. 

 and Ph.D., McGill University, 1950 and 1953. Dr. Hogg joined Bell 

 Telephone Laboratories in July 1953 and has worked at the Holmdel 

 Laboratory. He has been engaged in studies of artificial dielectrics for 

 microwaves, antenna problems, and over-the-horizon and millimeter 

 wave propagation as a member of the Radio Research Department. 

 During World War II Dr. Hogg was in the Canadian Army and spent 

 five years in Europe. From 1950 to 1951 he was engaged in research for 

 the Defense Research Board of Canada. He is a member of Sigma Xi. 



John L. Kelly, Jr., B.A. in 1950, M.A. in 1952, and Ph.D. in 1953, 

 all in Physics at the L^niversity of Texas. Dr. Kelly joined Bell Tele- 

 phone Laboratories in 1953 as a member of the Television Research De- 

 partment at the Murray Hill Laboratory. He has been engaged in ex- 

 perimental work on the nature of television pictures as w^ll as theoretical 

 investigations pertaining to applications of the Information Theory to 

 television. In 1944 he was commissioned a Navy pilot and served three 

 years. 



Archie P. King, B.S. California Institute of Technology, 1927. After 

 three years with the Seismological Laboratory of the Carnegie Institu- 

 tion of Washington, Mr. King joined Bell Telephone Laboratories in 

 1930. Since then he has been engaged in ultra-high-frequency radio re- 

 search at the Holmdel Laboratory, particularly with waveguides. For the 

 last ten years Mr. King has concentrated his efforts on waveguide trans- 

 mission and waveguide transducers and components for low-loss circular 

 electric wave transmission. He holds at least a score of patents in the 

 waveguide field. Mr. King was cited by the Navy for his World War II 

 radar contributions. He is a Senior Member of the I.R.E. and is a Mem- 

 ])er of the American Physical Society. 



J. G. LiNviLL, A.B., William Jewell College, 1941 ; S.B. in 1943, S.M. 

 in 1945 and Sc.D. in 1949, all in electrical engineering at Massachusetts 

 Institute of Technology. Dr. Linvill served at M. I. T. as assistant pro-
