Copy 

TO Mr. Grant Manson. Dept of State 4 Aug 50 

From Mr. F'riedman, AFSA-14 

Dear Grant: 

In Yardley's American Black Chamber (1931) the demise of that 

unit was ascribed to the- disapproval' of the activities by Sec State 

Stimson. A couple of years later Yardley himself .told me that he 

was in error in ascribing same to Stimson and- that it was in 

reality President Hoover. Do you have any way of verifying 

Yardley's later version from the official record1 

/s/ Friedman 

Dr. Sanford requested to take above original to Lt. Rowett & ask 

. I 

him to get the memo to Mr. Manson, if that 

is the correct channel
