Q.688

Two research papers were made public in 2012:

1. The Applications of Probability to Crypt
2. A Paper on the Statistics of Repetitions

The British department "GHCQ" (Government's Communications Headquarters) wasn't sure exactly when these were written, but figured it was about seventy years old because one of the paper's makes a reference to Adolf Hitler's age.

Who wrote these papers?
