WW2 Bletchley Park supervisor: Ray Scoot

Ray Scoot was just a teenager when he began working at Bletchley Park as a Hollerith team leader and supervisor in Hut 7 and Block C from June 1941 - June 1946.
This work was pre-computer mass data analysis using Hollerith punch cards.
Ray was in charge of one of the 6 teams in Hut 7, overseeing 25 girls and 2 engineers. He describes the Tetragram with which the team would look for patterns in the data - namely, 4-letter click repeats which would be passed to the code breakers to decipher.
He met his wife-to-be, Joan, at Bletchley - she was a Hollerith Operator in Block C.
