Abstract

Department of Mathematics Humboldt State University Arcata, CA 95521-4957 USA The accompanying photograph was sent to me by Mrs. Debbie Anderson, daughter of the late Joe Desch. It is a copy of the original in her family album and is reproduced here with her permission. The civilian on the left (hand on hip) has been identified as Alan Turing. The gentleman on the far right in the white suit has not been identified, but I have been told that he possibly is William Friedman. In the print dress behind the naval officer is Mrs. Joe Desch. The date of the photograph is July 15,1943. The occasion was a Purple Heart ceremony at NCR's Sugar Camp in Dayton, Ohio. I have long been interested in Alan Turing's trip (or trips) to the US during World War II. Little is known about the frequency or purpose, because the information is still classified. The only documented one that I know of is his visit with Claude Shannon to evaluate Bell Laboratories' scrambled telephone for use by staff in Churchill's and Roosevelt's offices. What follows is a combination of conjecture and second-hand information.

The accompanying photograph was sent to me by Mrs. Debbie Anderson, daughter of the late Joe Desch. It is a copy of the original in her family album and is reproduced here with her permission. The civilian on the left (hand on hip) has been identified as Alan Turing. The gentleman on the far right in the white suit has not been identified, but I have been told that he possibly is William Friedman. In the print dress behind the naval officer is Mrs. Joe Desch. The date of the photograph is July 15,1943. The occasion was a Purple Heart ceremony at NCR's Sugar Camp in Dayton, Ohio.

I have long been interested in Alan Turing's trip (or trips) to the US during World War II. Little is known about the frequency or purpose, because the information is still classified. The only documented one that I know of is his visit with Claude Shannon to evaluate Bell Laboratories' scrambled telephone for use by staff in Churchill's and Roosevelt's offices.

Joe Desch, under the auspices of US Naval Intelligence, was responsible for the design of special cryptographic equ...
