William M. Goodall, B.S., California Institute of Technology, 1928; 

 Bell Telephone Laboratories, 1928 — . Mr. Goodall has worked on re- 

 search problems in connection with the ionosphere, radio transmission 

 and early radio relay studies, radar modulators, and more recently micro- 

 wave radio relay systems. 



J. P. KiNZER, M.E., Stevens Institute of Technology, 1925. B.C.E., 

 Brooklyn Polytechnic Institute, 1933. Bell Telephone Laboratories, 

 1925 — . Mr. Kinzer's work has been in the development of carrier tele- 

 phone repeaters; during the war his attention was directed to investigation 

 of the mathematical problems involved in cavity resonators. 



J. R. Pierce, B.S. in Electrical Engineering, California Institute of 

 Technology, 1933; Ph.D., 1936. Bell Telephone Laboratories, 1936 — . 

 Engaged in study of vacuum tubes. 



Allen F. Pomeroy, B.S. in E.E., Brown University, 1929. Public 

 Service Electric and Gas Company, Electrical Testing Laboratory, 1923- 

 1925, 1926; Weston Electrical Instrument Corporation, 1927; Bell Tele- 

 phone Laboratories, 1929 — . Since 1936 Mr. Pomeroy has been principally 

 occupied in developing equipments to measure attenuations, phase shifts, 

 envelope delays, and reflection coefhcients for systems suitable for television 

 transmission, and during the war in the development of radar testing equip- 

 ment. 



W. G. Shepherd, B. S. in Electrical Engineering, University of Min- 

 nesota, 1933; Ph.D. in Physics, University of Minnesota, 1937. Bell 

 Telephone Laboratories, Inc., 1937 — . From 1937 to 1939 Dr. Shepherd 

 was engaged in non-linear circuit research. Since 1939 he has been engaged 

 in the design of electron tubes. 



I. G. Wilson, B.S. and M.E., University of Kentucky, 1921. Western 

 Electric Co., Engineering Department, 1921-25. Bell Telephone Labora- 

 tories, 1925 — . Mr. Wilson has been engaged in the development of am- 

 plifiers for broad-band systems. During the war he was project engineer in 

 charge of the design of resonant cavities for radar testing.
