 1948, 1949 and 1951; Institute of Rate Processes, University of Utah, 

 1949-1952; Bell Telephone Laboratories, 1952-. Dr. Anderson has been 

 engaged in the investigation of mechanical and electrical properties of 

 solids, with emphasis on glasses, and in studies of the mechanism of 

 plastic flow of amorphous bodies. A member of the mechanics division 

 of the Mathematics Department, he is now studying the strength and 

 flow properties of glasses under high pressure. Member of American 

 Physical Society, American Ceramic Society and Society of Glass Tech- 

 nology.

 Fellow, Bristol, England, 1947-1948; Bell Telephone Laboratories, 

 1948-. Dr. Gait has been engaged in research on the properties of solids, 

 especially of ferrites, with emphasis on their magnetic properties. Fellow 

 of the American Physical Society and member of Phi Beta Kappa. 



W. P. Mason, B.S. in E.E., University of Kansas, 1921; M.A., Ph.D., 

 Columbia, 1928. Bell Telephone Laboratories, 1921-. Dr. Mason has 

 been engaged principally in investigating the properties and applications 

 of piezoelectric crystals, in the study of ultrasonics, and in mechanics. 

 Fellow of the American Physical Society, Acoustical Society of America 

 and Institute of Radio Engineers and member of Sigmi Xi and Tau 

 Beta Pi. 



J. L. Merrill, Jr., B.S. and M.S., Pennsylvania State University, 

 1928 and 1930; ElUot Research Fellow, 1928-1930; American Telephone 

 and Telegraph Company, 1930-1934; Bell Telephone Laboratories, 

 1934-. Mr. Merrill spent his first years with the Laboratories on trans- 

 mission features of such projects as the time and weather announcement 

 systems and operator training programs. During World War II, he en- 

 gaged in planning system operation of air raid warnings as well as work 

 on tactical wire and radio networks for the armed forces. Since the war 

 he has been concerned with the design and application of negative
