with theoretical problems in solid state physics, including studies of 

 semiconductor materials. 



Mr. Bardeen, whose honors include an honorary Doctor of Science 

 degree from Union College, the Stuart Ballantine Medal, the John 

 Scott Medal, and the Buckley Prize, is a member of the National Acad- 

 emy of Sciences. He joined the University of Ilhnois in 1951.

 Technology in 1932, and a Ph.D. degree from the Massachusetts In- 

 stitute of Technology in 1936. He joined the staff of Bell Telephone 

 Laboratories in 1936. In addition to his many contributions to solid 

 state physics and semiconductors, Mr. Shockley has worked on electron 

 tube and electron multiplier design, studies of various physical phe- 

 nomena in alloys, radar development and magnetism. 



His many awards include an honorary degree from the University of 

 Pennsylvania, the Morris Liebmann Memorial Prize, the Buckley Prize, 

 the Comstock Prize and membership in the National Academy of 

 Sciences. Dr. Shockley left the Laboratories to form the Shockley Semi-
