C. H. Elmendorf, B.S., California Institute of Technology, 1935; 

 M.S., 1936; Bell Telephone Laboratories, 1936-. Mr. Elmendorf was 

 concerned with the development of coaxial cable transmission systems 

 from 1936 to 1955, except for the period from 1941-1945 when he worked 

 on airborne radar systems. In 1952 he started an exploratory program on 

 submarine cable systems. As Assistant Director of Transmission Sys- 

 tems Development since 1955, he has been responsible for development 

 of submarine cable systems. He is a senior member of the I.R.E. 



Bruce C. Heezen, B.A., University of Iowa, 1948; M.A., Columbia 

 University, 1952; Ph.D. 1956. After participating in a cruise of the 

 Woods Hole research vessel Atlantis in the summer of 1948, Mr. Heezen 

 held a fellowship in geology at Columbia, where he joined the staff of 

 the Lamont Geological Observatory when it was founded in 1949. As 

 submarine geologist, and now as senior scientist in charge of the sub- 

 marine geology program, he has been a member of numerous deep-sea 

 expeditions. In addition, he teaches a graduate course in submarine 

 geology on the Columbia campus. His work includes deep-sea topogra- 

 phy, sediments, and sedimentation processes; submarine photography 

 and deep-sea research instrumentation; and geologic, geoph3^sical, and 

 oceanographic exploration of the deep sea.
