development of microwave test equipment for radar systems, radio moni- 

 toring and jamming equipment. In 1948 he was made Director of Trans- 

 mission Apparatus Development, and in 1953 was appointed Director of 

 Military Communication Systems. He is a Fellow of the A.I.E.E. and a 

 Senior Member of the I.R.E.

R. W. Ketchledge, B.S., Massachusetts Institute of Technology, 

 1942; M.S., Massachusetts Institute of Technology, 1942; Bell Tele- 

 phone Laboratories, 1942-. During World War II Mr. Ketchledge as- 

 sisted in research related to infra-red detecting devices and in the de- 

 velopment of sonar devices. After the war he spent two years working 

 on the development of the Key West-Havana submarine cable system 

 and from 1949-53 he was in charge of systems design for the L3 coaxial 

 system. He was recently appointed Electronic Apparatus Development 

 Engineer and is responsible for gas tube and storage tube development.

 M.A., University of Southern California, 1928. Southern California 

 Edison Company, 1928-30; Bell Telephone Laboratories, 1930-. Since 

 joining the Laboratories, Mr. Kinsburg has worked on research and 

 development of broad band carrier systems using coaxial cable as the 

 transmission medium. This includes amplifier development, study of 

 cross-talk in coaxial conductors, requirement studies for coaxial equip- 

 ment, equalization studies and television echo requirements and, cur- 

 rently, quality control studies of the L3 system components and re- 

 liability studies of the long-range submarine cable development. Member 

 of the Institute of Radio Engineers, American Association for the Ad- 

 vance of Science, and Society for Social Responsibility in Science.
