Warsaw, Conference on Enigma Machine


The Conference took place in Warsaw in 2009. It was about Polish contribution during WW2 for intelligence, counter-intelligence and mostly for deciphering the Enigma Machine traffic.
I was invited and produced a paper about SOE in Portugal. 
I found the news about the event, today, here.


Flowers were a form to pay the tribute to the man who did the work to crack the German cypher machine, Marian Rejewski.
