 versity; Bell Telephone Laboratories, 1949-. Since completing the Lab- 

 oratories' Communications Development Training Program in 1952 Mr. 

 Bobeck has been engaged in the design of both communications and 

 pulse transformers and more recently in the design of solid state memory 

 devices. Member LR.E., Eta Kappa Nu and Tau Beta Pi. 



B. C. Bellows, Jr., B.S., Cornell LTniversity, 1936; General Electric 

 Co., 1936-39; Bell Telephone Laboratories, 1939-. From 1939 to 1941 

 Mr. Bellows was engaged in engineering trial installations of telephone 

 equipment, particularly multi-channel coaxial cable equipment. During 

 World War II he specialized in the mechanical design and engineering of 

 airborne radars. From 1945 to 1957 he was engaged in the design of 

 circuits and equipment for point-to-point microwave radio relay systems 

 for telephone and television transmission. On May 1, 1957 he was named 

 Transmission Measurement Engineer. Member Eta Kappa Nu and Phi 

 Kappa Phi. 



Charles A. Desoer, Dipl. Ing., University of Liege (Belgium), 1949; 

 Sc.D. Massachusetts Institute of Technology, 1953; Bell Telephone 

 Laboratories, 1953-. Since joining the Laboratories Mr. Desoer has 

 specialized in linear and transistor network development in the Trans- 

 mission Networks Development Department. Senior Member LR.E. 



R. Shiels Graham, B.S., LTniversity of Pennsylvania, 1937; Bell 

 Telephone Laboratories, 1937-. His work has been with the design of 

 equalizers, electrical wave filters and similar apparatus for use on long- 

 distance coaxial cable circuits, microwave systems and both telephone 

 and television transmission. During World War 11, Mr. Graham de- 

 signed circuits for electronic fire control computers for military use. He 

 also developed methods for computing network and similar problems 

 on a digital relay computer. He presently supervises the video and inter- 

 mediate frecjuency network group. He is a senior member of the LR.E., 

 and a member of Tau Beta Pi, and Pi Mu Epsilon.
