"Events in the Daily Life of a Cryptanalyst". Bj Mujor William 

F. Fried.man, S.ir:;.-Reft,, of Washington, D.C. T.le talk will be 

illustrated with lantern slides and several interesting exhibits. 

Major Friedman is Chief of the Code and Cipher Section in the Office of the 

Chief Signal Officer, War Department, wilere he is in eharge of the compilation 

ot all codes and ciphers employed by the .Army. He l1as probably had more practical 

experience in the little-known field of cryptography than any oth~r person in the 

United States. In 1916, while in charge of the Department of Genetics at the 

Riverbank Laboratories, Geneva, Illinoi~, ne became interested in the subject as 

a hobby. Largely through his own initiative he must~red wnat little information 

was available, and presently he began ma.ki..g original contributions to the field. 

Soon the imminence of our entry into the World War led the government to ask for · his services, as a result of which he beca."!le the director of a school in which 

rnany of our officers assigned to decoding enemy documents were trainedl Leter he 

was commissioned and sent to .Alnerican G.H.~. as a member ot the Radio Ir.telligence 

section of the Generar-staff'. After the· we.r his -services were considered 

valuable enough to lead the War Deparunent to ask that he continue his work with 

the Signal Corps, where he is llJften celled upon by other government departmentsand sometimes, as in the case of the Oil Investig~tion, by the Senate - in his 

expert capacity.
