Dear Lawrence: 

REF ID:A70016 

' 

August 19, 1947 

' .. 

.. 

Yo~ letter o~ 14 August 1947 was forwarded to me from the Office 

of the Chief Signal Offic.er. I am acknowledging its receipt at once, 

thinking that you may want to have early information on the matter 

about which you write. · 

· I am turning your letter over to the proper section of our Staff 

for handling, as the :people there are in the best.position to give · you definite answers to the quest~ons · you ask. 

· I remember your participation- in one of our classes for reserve 

·officers and.pres'WDably there should be some officia:l record thereof, ~s well as of your work in the .Army Extens~on Subcourses we conducted. 

. I am glad to tell you that my health has improved a great deal since 

our last meeting, and I have been· on the job quite steadily ever since. 

Reciprocating your kind personal regards, 

Sincerely yours, 

~illiam F. Friedman .. 
... , .. ,.... • Mr~ William F. Friedman, 

Office of the Chief Signal O~ficer, 

Washington, D •. c. 

Mr dear Mr. Friedman: 

115 Branch Avenue 

Red Bank; New Jersey. 

14 August; 1947. 

.. Perhaps you will recall my attendance at o:i:ie of 

your cl.asses for 14 days, in 1930 if I recall correctly, at Munitions 

Building. While this was a short course, considering only hours involved, I have felt that the knowledge of principles of operation 

gained in make-up and break-down of systems, and other valuable prin-

'ciples, have ·given me a strong basis of fundament~ls on which to 

work. This seemed to be proven in the ease with which I was able to 

accomplish later correspondence lessons in crypto~aphy. 

It ~ems.that a record of my taking this course 

under your direction never became part of my record on form 66-2. How 

can I get it.recorded thereon for a Crypt. spec. No? 

. In a few days· I expect to put in an application 

for return to active duty mentioning the above tour of duty.· I have 

no way of knowing whether it will carry a~propriate significanc.e, 

usfficient to get back where I left off February 20th 47, but ~ think 

it worth the effort, as. I was fascinated by the work involved and 

wouJ,.d like to put the wor~ I have already put into the study to some 

practical use for the Army and myself, as well. If correspondence 

courses are again available, I'd like to take up the work and·study 

again - perhaps you can a·dvise me on this procedure. I should have 

established clearance requirements, having completed M.I. course at 

Ritchie (IJid.), 17 July, 43. . · · 

I haven't run across a single ~ember or that 

class since Feb. 1942. Have often wondered whether any of them got 

into the wo~k during the war. Do hope you are feeling betier than 

when I last saw you. 

Best personal regards, 

Isl P.·M. Lawrence
