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

 sity, 1947; Ph.D., Purdue University, 1949; Studies at Purdue under- 

 taken as the result of a scholarship from Cairo University for four years 

 of graduate work. Bell Telephone Laboratories, 1950-. For the past 

 three years he has been a member of the Switching Apparatus Develop- 

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

 research work on contact physics and engineering. Current projects in- 

 clude fundamental studies of gas discharge phenomena between con- 

 tacts, 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, Pi Tau 

 Sigma, the American Physical Society, and an associate member of the 

 A.S.M.E. 



Rosemary E. Cox, B.A., Ladycliff College, 1949; M.S. Fordham 

 University, 1950; Bell Telephone Laboratories, 1951-. Miss Cox, who 

 taught high school mathematics for a year before coming to the Labora- 

 tories, has been engaged in fundamental studies of contact physics. She 

 won a New York State University Scholarship and scholarships from 

 Ladycliff and Fordham. 



Gerald V. King, B.S., Carnegie Institute of Technology, 1920; 

 Western Electric Company, 1921-24; Bell Telephone Laboratories, 

 1925-. Mr. King analyzed customer orders for step-by-step and manual 

 systems for three years before turning to the design and checking of 

 manual and dial PBX and community dial offices. From 1932 to 1939 

 he engaged in fundamental studies and development of new local and 

 toll crossbar systems. He was involved in military work from 1939 to 

 1944 and since then he has been concerned with design and development 

 of AMA accounting centers, central offices and crossbar tandem sys- 

 tems. He was appointed Switching Systems Development Engineer in 

 1952.
