A few years later I mentioned it to another Apple employee, who immediately said that he thought it was a myth. It may have started around the time of the 2001 film about the Bletchley Park code breakers, Enigma, or it may have just resurfaced then. He checked with Apple headquarters, and although they were non-committal, it was clear that that Turing story was not official Apple history. Other theories were advanced. The apple represented knowledge, as in the biblical story of Adam and Eve, or referenced the falling fruit that led Sir Isaac Newton to the concept of gravity. Supporters of the latter theory note the name of Apple's handheld PDA, the Newton, but that was more than a decade after the creation of the logo.
