The Enigma story, and the misattributions of credit:
In U-571, Hollywood gave the credit for the Enigma code-cracking heroics of World War Two to the Americans. In the British thriller Enigma, out today, the praise is given to the English. Now, if a protest from the Polish embassy in London is to be believed, it was the Poles that done it after all.
From what I’ve read, the Polish cryptographers are certainly missing out on a lot of the credit they’re rightly due.
