An Engilsh Codebreaker, John Somer, was active in the 1560s and the 1570s, as noted in "Ciphers during the Reign of Queen Elizabeth I". On the other hand, the name "John Somer" is often mentioned in 1584-1585 as a secretary to Ralph Sadler, keeper of Mary, Queen of Scots in captivity. I have long wondered whether these are the same person, but now the question is affirmatively answered by Nadine Akkerman and Pete Langman (2024), Spycraft, which induced me to reexamine a little bit. I now added a section "John Somer in the 1580s."
(2024/09/08) I remembered my article on Mary's ciphers mentions Walsingham's forwarding Mary's letter to be deciphered by Somer in October 1582. I now added a mention of this.
