Reuben E. Alley, Jr., B.A., University of Richmond, 1938; E.E., 

 Princeton University, 1940; Ph.D., Princeton University, 1949. Massa- 

 chusetts Institute of Technology, Radiation Laboratory, 1942 and 1943; 

 University of Richmond, 1948-51; Bell Telephone Laboratories, 1952-53. 

 While at Bell Laboratories, Mr. Alley was engaged in investigations of 

 the magnetic properties of ferrites, with particular interest in frequencies 

 above 20 megacycles. He recently accepted an appointment at the Uni- 

 versity of Richmond as an associate professor of physics. Member of 

 the American Physical Society, A.I.E.E., I.R.E., Phi Beta Kappa and 

 Sigma Xi. 



M. M. Atalla,B.S., Cairo University, 1945; M.S., Purdue University, 

 1947; Purdue University, Ph.D., 1949; Studies at Purdue undertaken as 

 the result of a scholarship from Cairo University for four years of gradu- 

 ate work. Bell Telephone Laboratories, 1950-. For the past three years 

 he has been a member of the Switching Apparatus Development Depart- 

 ment, in which he is supervising a group doing fundamental research 

 work on contact physics and engineering. Current projects include 

 fundamental studies of gas discharge phenomena between contacts, 

 their mechanisms, and their physical effects on contact behavior; also 

 fundamental studies of contact opens and resistance. In 1950, an article 

 by him was awarded first prize in the junior member category of the 

 A.S.M.E. He is a member of Sigma Xi, Sigma Pi Sigma, and Pi Tau 

 Sigma, and a junior member of the A.S.M.E. 



William R. Bennett, B.S. in E.E., Oregon State College, 1925; 

 M.A., Columbia University, 1928; Ph.D., Columbia, 1949. Bell Tele- 

 phone Laboratories, 1925-. His early Laboratories projects included 

 work on wire transmission problems, particularly the development of 

 terminal apparatus in the voice and telegraph range, the design of cir- 

 cuits for television, and submarine cable telephony. Concerned with the 

 coaxial cable in 1935, he spent several years working on the require- 

 ments and measuring techniques applicable to the load rating of multi- 

 channel repeaters. His work during World War II was directed to a
