many of the klystrons used in radar equipment. Later he again be- 

 came concerned with the development of long-hfe tubes for submarine 

 telephone cables. He has been awarded several patents on electron tube 

 construction and operation. He is a FeUow of the I.R.E. and a member of 

 the American Physical Society. 



George W. Meszaros, B.E.E. 1939, College of the City of New York; 

 Bell Telephone Laboratories, 1926-. INIr. ]\leszaros started his Bell System 

 career in the Systems Drafting Department. After spending a short time 

 in several engineering groups of the System Department, he transferred 

 to the Power Development Department in 1941. Here he has specialized 

 in electronically controlled power equipment. Currently he is in charge of 

 a group designing transistorized power supphes for the electronic switch- 

 ing system and for several mihtary projects. 



G. H. Metson, B.Sc. in Engineermg, University of London 1931; 

 M.Sc. in 1938 and Ph.D. in AppHed Science and Technology, Queens 

 Universitj% Belfast 1941. Dr. Metson is in charge of the Thermionics 

 Group at the Post Office Research Station and is particularly concerned 

 with oxide coated cathodes and problems of tube life. He was responsible 

 for the tubes used in the British submerged repeaters. Member of the

 Electrical Engineers. 



Elliott T. Mottram, B.S. Columbia University 1927, M.E. 1928; 

 Western Electric Company 1922-25; Bell Telephone Laboratories, 1928-. 

 Mr. Mottram's first assignments were in the development of disc re- 

 cording and reproducing machines and equipment. Later he was con- 

 cerned with sound on film recording and reproducing equipment, and 

 with tape recording. From 1939 to 1950, he was engaged in development 

 of airborne radio and radar equipment, electronic computer and bomb 

 sights, and airborne homing missiles. As Dh*ector of Transmission 

 Systems Development since 1950, he has been concerned with the de- 

 velopment of transmission systems and equipment for military purposes, 

 transmission test equipment, and television and wire transmission 

 systems. In this capacity, he was responsible for technical liaison with 

 the British Post Office on submarine cable matters and was in charge of 

 Laboratories' activities in this field. He is a member of the A.S.M.E. 

 and I.R.E.
