Richard C. Boyd, B.S., Northwestern University, 1946; B.S.E.E., 

 University of Michigan, 1947; M.S.E.E., University of Michigan, 1948; 

 Bell Telephone Laboratories, 1948-. After completion of the Labora- 

 tories Communication Development Training program in 1950, Mr. 

 Boyd was concerned with transmission engineering and systems studies. 

 He was a supervisor during the exploratory trial of experimental PI 

 carrier in 1953 and 1954. He is now responsible for transmission engineer- 

 ing of PI carrier for rural subscriber use, and for adaptation of P and 

 Nl carrier to exchange trunk use. He is a member of Tau Beta Pi and 

 Phi Kappa Phi. 



Robert W. Dawson, Newark College of Engineering; Rutgers Uni- 

 versity; Bell Telephone Laboratories, 1941-. All of ]\Ir. Dawson's work 

 has been with the Radio Research Department. Together with A. C. 

 Beck, he was concerned with conductivity measurements at microwave 

 frequencies, and they were co-authors of an article on this subject. INlr. 

 Dawson, a member of the Institute of Radio Engineers, worked on the 

 Manhattan Project at Los Alamos while serving in the Army from 1942 

 to 1946. 



George Feher, B.S, in Engineering Physics, University of Cali- 

 fornia, 1950; M.S.E.E., University of California, 1952; Ph.D. in Physics, 

 University of California, 1954; Bell Telephone Laboratories, 1954-. Dr. 

 Feher has been a member of the Semiconductor Research Department 

 since joining the Laboratories. He has been engaged particularly in 

 studies of electron spin resonance absorption, and is the author of several 

 articles on this subject. He is a member of the American Physical So- 

 ciety, the Institute of Radio Engineers, and Sigma Xi. 



John D. Howard, B.E.E., University of Louisville, 1947; Southern 

 Bell Telephone Company, 1947-. After a year and a half in the Plant 

 Department at Southern Bell, Mr. Howard joined the Engineering De- 

 partment and remained there until late 1952. At that time he was called 

 to the 0. & E. Department of the A. T. & T. Co. where he was con- 

 cerned with exchange transmission. After completing this assignment he
