W. R. Bennett, B.S., Oregon State College, 1925; A.M., Columbia Uni- 

 versity, 1928. Bell Telephone Laboratories, 1925-. Mr. Bennett has been 

 engaged in the study of the electrical transmission problems of com- 

 munication. 



Carl R. Englund, B.S. in Chemical Engineering, University of South 

 Dakota, 1909; University of Chicago, 1910-12; Professor of Physics and 

 Geolog>', Western Maryland College, 1912-13; Laboratory Assistant, Uni- 

 versity of ]Michigan, 1913-14. Western Electric Company, 1914-25; Bell 

 Telephone Laboratories, 1925-. As radio research engineer Mr. Englund 

 is engaged largeh' in experimental work in radio communication. 



D. K. Gannett, B.S. in engineering. University of Minnesota, 1916; E.E. 

 University of Minnesota, 1917. American Telephone and Telegraph Com- 

 pany, Engineering Department, 1917-1919; Department of Development 

 and Research, 1919-1934; Bell Telephone Laboratories, Inc. 1934-. Prior 

 to October 1942 Mr. Gannett, as Toll Transmission Engineer, was concerned 

 with the transmission requirements of toll systems including program cir- 

 cuits. Since then, as Circuit Research Engineer, he has directed a group 

 engaged in research and development on war projects. 



Iden Kerney, B.S. Harvard University, 1923. American Telephone and 

 Telegraph Company, 1923-1934; Bell Telephone Laboratories, Inc. 1934-. 

 Before the war Mr. Kerney was in charge of the laboratory in which experi- 

 mental work on program transmission was conducted. Since early in 1942 

 he has been engaged full time on war projects. 



R. A. Sykes, Massachusetts Institute of Technology', B.S. 1929; M.S. 

 1930. Columbia L^niversity, 1931-1933. Bell Telephone Laboratories, 

 Research Department, 1930-. Mr. Sykes has been engaged in the applica- 

 tions of quartz crystals to broad-band carrier systems as filter and oscillator 

 elements. Other work has included the application of coaxial lines as ele- 

 ments of filter networks and more recently the design and development of 

 quartz crystals for radio frequency oscillators. 



G. W. WiLLARD, B.A., University of Minnesota, 1924; M.A., 1928; In- 

 structor in Physics, University of Kansas, 1927-28; Student and Assistant, 

 University of Chicago, 1928-30. Bell Telephone Laboratories, 1930-. Mr. 

 Willard's work has had to do with special problems in piezo-electric crystals.
