Laboratories Mr. Mallina worked initially in acoustical research where 

 he developed the first magnetic telephone message recorder and the 

 five-reed telephone set. From 1936 on he was engaged in fundamental 

 development on machine switching apparatus, first on AMA, later 

 with the wire spring relay project. In connection with the latter, he 

 developed the solderless. wrapped connection. Mr. Mallina is also a 

 research associate at New York University, Department of Education. 



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 engated 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 Sigma Xi and Tau 

 Beta Pi. 



J. W. McRae, B.S. in E.E., University of British Columbia, 1933; 

 M.S., California Institute of Technology, 1934; Ph.D., California In- 

 stitute of Technology, 1937. Bell Telephone Laboratories, 1937-42, 

 1945-. U. S. Army 1942-45, where he attained the rank of Colonel and 

 served as Deputy Director of the Engineering Division of the Signal 

 Corps Engineering Laboratories. Returning to Bell Telephone Labo- 

 ratories in 1945, Dr. McRae became Director of Radio Projects and 

 Television Research in 1946; Director of Electronic and Television 

 Research, 1947; Assistant Director of Apparatus Development I, 1949; 

 Director of Apparatus Development I, 1949; Director of Transmission 

 Development, 1949; Vice President, 1951. Legion of Merit, 1945. Presi- 

 dent of the Institute of Radio Engineers, 1953. Member of the A.I.E.E. 

 and Sigma Xi. 



T. F. OsMER, E.E, Polytechnic Institute of Brooklyn, 1935. Bell 

 Telephone Laboratories, 1920-. As a member of the Physical Research 

 Department until 1952, Mr. Osmer was primarily concerned with trans- 

 ducers, including transmitters, receivers, loudspeakers, and high quality 

 microphones. During World War II he worked on military contracts, 

 and since the war he has been occupied with carbon contact studies, 

 and more recently with studies of the solderless wrapped connection, 

 using photoelastic techniques. 



R. C. Prim, received a B.S.E.E. degree from the University of Texas 

 in 1941, and M.A. and Ph.D. degrees from Princeton University in 1949'. 

 Following graduation from college, he was employed by General Elec- 

 tric Company in Schenectady until 1944, and then, as an ensign in the
