American Standards Association Sectional Committee C63, Harvard 

 Engineering Society, and Phi Beta Kappa. 



Edmund A. Veazie, B.A. in Physics, Univ. of Oregon, 1927; Bell 

 Telephone Laboratories, 1927-. His early assignments included the 

 design of multi-grid tubes for use in aircraft radio receivers, police 

 transmitters, and carrier telephone systems. During World War H he 

 concentrated on tubes for radar and other military applications, in- 

 cluding proximity fuses and gun directors. Since then he has been 

 engaged principally in the design, fabrication control, testing, and selec- 

 tion of tubes for use in submarine telephone cable systems. He holds 

 several patents on electron tubes and associated circuits. He is a Senior 

 Member of I.R.E. and a member of Phi Beta Kappa. 



D. C. Walker, B.Sc. in Engineering and Diploma of the Imperial 

 College from the City and Guilds College, University of London, 1937; 

 British Post Office Research Branch 1938. Mr. Walker's early work Avas 

 on interference and protection problems and during the war on special 

 investigations for the services. Later engaged on development and equip- 

 ment for carrier telephone systems, and since 1946 has specialized on 

 submerged repeater systems. He is in charge of the group concerned with 

 the design of the internal electrical unit of the rigid transatlantic tele- 

 phone cable repeaters and the special terminal equipment. Associate 

 Member of The Institution of Electrical Engineers. 



V. G. Welsby, B.Sc. London University 1934; Ph.D. London Univer- 

 sity 194G; Research Branch of the British Post Office, 1936. Dr. Welsby 

 was at first a member of a group dealing with the design of multichannel 

 carrier apparatus. Since 1947 he has been engaged in submerged repeater 

 development, and during the last few years, has been in charge of the 

 group concerned with the mechanical design of repeater housings and 

 glands, and with the laying of rigid repeater systems. His Ph.D. degree 

 was awarded for his work on dust-cored inductors. He is the author of 

 a text book on inductor theory and design. Associate Member of The 

 Institution of Electrical Engineers. 



M. C. WooLEY, B.S. in E.E., Ohio Northern Univ., 1929; Bell Tele- 

 phone Laboratories, 1929-. Mr. Wooley was engaged in the development 

 and design of inductors until 1935. Capacitor development then occupied 

 his attention until 1949, concluding with the development and produc-
