During the 1st World War, as an officer of the Austro-Hungarian Empire’s army, he fought in the region of Sądecki and Niski Beskid where he was taken prisoner by Russians. After being freed from captivity, he joined the Polish army which was being formed in Siberia. During the October Revolution he was taken captive again, this time by Soviets from whom he escaped. In independent Poland Gwido Langer was appointed a Head of the Cipher Bureau of the Polish Armed Forces in the period when it achieved its greatest successes. After the outbreak of the 2nd World War, together with the Bureau he was evacuated to France where he worked by 1943 i.e. when the Germans took over the so-called “free zone”. He made an unsuccessful attempt to get through the Pyrenees to Spain. After being betrayed by a French guide, he was taken prisoner by the Germans and remained in captivity by the end of the war. However, Gwido Langer never disclosed the secret of breaking the Enigma. After the war, he went to the Great Britain where he died in unclear circumstances. His remains were brought to Poland on 1 December 2010 and buried on the Municipal Cemetery in Cieszyn.
