||Brigadier John Hessell Tiltman (b. 25 May 1894) was a British Army officer who worked in intelligence, often at or with the Government Code and Cypher School (GC&CS) starting in the 1920s. His intelligence work was largely connected with cryptography, and he showed exceptional skill at cryptanalysis. His work in association with Bill Tutte on the cryptanalysis of the Lorenz cipher, the German teleprinter cipher, called "Tunny" (for tunafish) at Bletchley Park, led to breakthroughs in attack methods on the code, without a computer.

||Calvin Souther Fuller (b. May 25, 1902) was a physical chemist at AT&T Bell Laboratories where he worked for 37 years from 1930 to 1967. Fuller was part of a team in basic research that found answers to physical challenges. He helped develop synthetic rubber during World War II, he was involved in early experiments of zone melting, he is credited with devising the method of transistor production yielding diffusion transistors, he produced some of the first solar cells with high efficiency, and he researched polymers and their applications.
