My apology to readers of this journal for the error of fact which, due to my submission, appeared on page 10 of the Annals, Vol. 15, No. 1, 1993. The individual on the left in the photograph is not Alan Turing, and the tentative identification of the gentleman on the extreme right as William Friedman is also incorrect. The remaining information in the note is correct.

I accept full responsibility for the error. Although I had circulated the photograph among eight or 10 individuals who had known and worked with Alan luring before and during World War II, I should have been more wary. I should have carefully checked additional UK cryptographic sources for any evidence that Turing was in the US in the summer of 1944. I have now done that, although there were times when my attempts to check various classified sources were rebuffed. I finally was ready to admit that he just did not return to the US after his visit to Bell Labs in the early part of the year.

In November 1994, while in Cambridge (UK), I had lunch with Shaun Wylie, one of Turing's colleagues at Bletchley. When I showed him the photo, he insisted it was not Turing. When I returned to the US, I contacted Mrs. Debbie Anderson, who had provided the original, to see if she could arrange with NCR to make an improved copy. She was successful, and I sent this one to Wylie. When he received it, he showed it to Sir Harry Hinsley and Mrs. Hinsley. Harry knew Turing both in Cambridge and at Bletchley. Mrs. Hinsley also knew him, since they regularly invited him to dinner when he was in Cambridge. All agreed the figure was not Turing.
