In the above photo, I don’t recognize the Captain, but Frank Raven on the far right was my boss there for many years, both in OP20GY4 & NSA. Frank was one of the most successful cryptanalyst in WWII, working on the IJN’s JN-25---was a L/Cdr by the end of the War & then at NSA a GS-18. Died about 10 years ago. R/ Don McDonald
