Arthur B. Crawford, B.S.E.E. 1928, Ohio State University; Bell 

 Telephone Laboratories 1928-. Mr. Crawford has been engaged in radio 

 research since he joined the Laboratories. He has worked on ultra short 

 wave apparatus, measuring techniques and propagation; microwave 

 apparatus, measuring techniques and radar, and microwave propagation 

 studies and microwave antenna research. He is author or co-author of 

 articles which appeared in The Bell System Technical Journal, Pro- 

 ceedings of the I.R.E., Nature, and the Bulletin of the American Me- 

 teorological Society. He is a Fellow of the I.R.E. and a member of Sigma 

 Xi, Tau Beta Pi, Eta Kappa Nu, and Pi Mu Epsilon. 



C. Chapin Cutler, B.S. 1937, Worcester Polytechnic Institute. Bell 

 Telephone Laboratories 1937-. Mr. Cutler's early work was in research 

 related to the problems of the short wave multiplex radio transmitter. 

 During World War H he was engaged in research on the proximity fuse 

 and microwave antennas for radar use. Since the war he has been con- 

 cerned with research on the microwave amplifier and the traveling wave 

 tube. Mr. Cutler is a member of the LR.E. and Sigma Xi. 



Harry H. Felder, B.S. in Electrical and Mechanical Engineering, 

 ClemsonA. and M., 1918. After some months in the U. S. Signal Corps 

 he joined the Engineering Department of the American Telephone and 

 Telegraph Company in 1919. He joined the Laboratories in 1934. He 

 has been engaged in general transmission problems in connection with 

 telephone repeater development and toll circuit layout and switching. 

 During World War H, Mr. Felder assisted in the development of a 

 method of lapng telephone wires from airplanes. Since that time he has 

 continued to work on the transmission aspects of intertoll trunk design, 

 switching, maintenance and loading. He was also associated with adapt- 

 ing of cable carrier circuits for radio broadcast networks. Mr. Felder is a 

 member of Tau Beta Pi. 



J. H. FoRSTER, B.A. 1944, M.A. 1946, University of British Colum- 

 bia; Ph.D. 1953, Purdue University; Bell Laboratories 1953-. Since join-
