262 THE BELL SYSTEM TECHNICAL JOURNAL, JANUARY 1953 



Kenneth Bullington, B.S. in E.E., University of New Mexico, 

 1936; S.M., Massachusetts Institute of Technology, 1937; Bell Tele- 

 phone Laboratories, 1937-. Until World War II, Mr. Bullington was oc- 

 cupied with systems engineering work on wire transmission circuits. 

 Since 1942, he has been concerned with transmission engineering on radio 

 systems, especially with radio propagation studies. Member of I.R.E., 

 Phi Kappa Phi, Sigma Tau, and Kappa Mu Epsilon. 



R. H. CoLLEY, A.B., Dartmouth College, 1909; A.M., Harvard Uni- 

 versity, 1912; Ph.D., George Washington University, 1918; Austin 

 Teaching Fellow in Botany, Harvard University, 1910-12; Instructor in 

 Botany, Dartmouth College, 1909-10 and 1912-16; Pathologist, Division 

 of Forest Pathology, Bureau of Plant Industry, U. S. Department of 

 Agriculture, 1916-28. Bell Telephone Laboratories, 1928-1952. Dr. Col- 

 ley w^as chairman of Committee 05 — Wood Poles, of the American 

 Standards Association for nearly twenty years. He was president of the 

 American Wood-Preservers' Association 1943-44. During his years with 

 the Laboratories he worked particularly on development and research 

 problems connected with material and preservative treatment specifica- 

 tions for poles and other timber products used in outside plant. His more 

 recent activities were directed tow^ard improvement of laboratory tech- 

 niques for evaluating wood preservatives, and toward the development 

 of a coordinated plan for fundamental research on oil preservatives. He 

 was Timber Products Engineer for the Laboratories from 1940 to 1950, 

 and Timber Products Consultant from 1950 to 1952. His article in this 

 issue of the Journal was prepared before his retirement on May 31, 

 1952. 



Karl K. D arrow, B.S., University of Chicago, 1911. He studied at 

 the Universities of Paris and Berlin in 1911 and 1912, specializing in 

 physics and mathematics; Ph.D., University of Chicago, 1917. He then 

 joined the staff of Bell Telephone Laboratories, at that time known as 

 the Engineering Department of Western Electric Company. Here his 

 work has included the study, correlation, and representation of scientific 

 information for his colleagues, keeping them informed of current ad- 

 vances made by workers in fields related to their own activities. As a 

 corollary to his work, Dr. Darrow appears from time to time before 

 scientific and lay audiences to lecture on current topics in physics and 

 the related sciences. He has taken an active interest in education, teach- 

 ing physics during summer and other sessions at Stanford, Chicago, and 

 Columbia Universities and at Smith College. From 1944 to 1946, he served
