Polish mathematicians who solved the Enigma machine

Marian Adam Rejewski ( [ˈmarjan reˈjefski] (help·info); 16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist who, in 1932, solved the Enigma machine, the main cipher device used by Germany. The success of Rejewski and his colleagues jump-started British reading of Enigma in World War II, and the intelligence so gained, code-named "Ultra", contributed, perhaps decisively, to the defeat of Nazi Germany.

Henryk Zygalski ( ['xɛnrɨk zɨ'galski] (help·info); 1906 - 1978) was a Polish mathematician and cryptologist who worked at breaking German Enigma ciphers before and during World War II.

Tadeusz Pełczyński (Warsaw, February 14, 1892 – January 3, 1985, London) was a Polish Army major general (generał brygady), intelligence officer and chief of the General Staff's Section II (the military intelligence section)

The Poles' gift, to their British and French allies, of Enigma decryption at Warsaw on July 26, 1939, just five weeks before the outbreak of World War II, came not a moment too soon. Former Bletchley Park mathematician-cryptologist Gordon Welchman has written: "Ultra [the British Enigma-decryption operation] would never have gotten off the ground if we had not learned from the Poles, in the nick of time, the details both of the German military... Enigma machine, and of the operating procedures that were in use." After the war, Britain's Prime Minister Winston Churchill was to tell King George VI: "It was thanks to Ultra that we won the war."

Jerzy Witold Różycki (pronounced ['jʒɨ ru'ʒɨʦki]; Olshana, near Kiev, Ukraine, July 24, 1909 — January 9, 1942, Mediterranean Sea, near the Balearic Islands) was a Polish mathematician and cryptologist who worked at breaking German Enigma-machine ciphers.

And it was also the british who captured the enigma machines

Without the british there would have been no enigma machines to crack. :)

How is that then?

something the poles did little of during the war

we captured the enigma machines to study. We captured them through fighting, something the poles did little of during the war.

The debate is not on who captured the machines, but on who decoded them.

That stupid statement would be similar to my stating, from an American perspective, the British did very little fighting, either.

Trouble is, although the whole thing was a combined effort to beat a common enemy, some of the descendants of those from all parties involved have to try to prove how big their -------s are.

Polish mathematicians who solved the Enigma machine

no mention of the Poles' role

The bomba, or bomba kryptologiczna (Polish for "bomb" or "cryptologic bomb") was a special-purpose machine designed about October 1938 by Polish Cipher Bureau cryptologist Marian Rejewski to break German Enigma-machine ciphers.

The cyclometer was a cryptologic device designed, "probably in 1934 or 1935," by Marian Rejewski of the Polish Cipher Bureau's German section (BS-4) to facilitate decryption of German Enigma ciphertext

The card catalog, or "catalog of characteristics," in cryptography, was a system designed by Polish Cipher Bureau mathematician-cryptologist Marian Rejewski, and first completed about 1935 or 1936, to facilitate decrypting German Enigma ciphers

I knew the story, but didn't know about the monument in Poznań. I hope to see it next summer.

The PZL.37 Łoś (Polish: moose) was a Polish twin-engine medium bomber, used in the Invasion of Poland in 1939. Thanks to the laminar-flow wing it was one of the most modern bombers in the world before World War II.

The PZL.37 was designed in the mid-1930s at the PZL factory in Warsaw by Jerzy Dąbrowski.

The 7TP was the Polish light tank of the Second World War. A development of the British Vickers 6-ton, it was significantly better armed than its most common opponents, the German Panzer I and Panzer II.

Karabin przeciwpancerny wzór 35 (abbreviated "kb ppanc wz. 35"; "anti-tank rifle, model 35"), was a Polish 7.92 mm anti-tank rifle used by the Polish Army during the Polish Defensive War of 1939. It was also known by its code name, kb Urugwaj (kb Ur), or by the name of its designer, Józef Maroszek.

The effective range was 300 metres and the weapon was effective against all German tanks of the period (the Panzer I, II and III, as well as the Czech-made LT-35 and LT-38) at 100 meters. At up to 400 meters it could destroy all lightly-armored vehicles. It could penetrate 15 mm of armor, sloped at 30° at 300 m distance, or 33 mm of armor at 100 m. Interestingly, an Italian manual stated maximum penetration as 40 mm.

The Mine detector (Polish) Mark I was a metal detector for landmines developed during World War II in the winter of 1941/1942 by Polish lieutenant Józef Kosacki.
