One of the most interesting stories I read was that the original rainbow apple logo was a tribute to Alan Turing, an English mathematician, logician, cryptanalyst and computer scientist, whose concepts played a considerable part in the development of the modern computer system. Turing was homosexual and heavily persecuted for this which was, at the time, illegal in the UK. In 1954 he committed suicide, by cyanide poising. A half eaten apple was found with his body, which was thought to have contained the cyanide. Hence forth a half eaten apple was a symbol for Alan Turing and his life’s work; and thus the apple logo, with a bite out of it was a reference to this. Seemingly the rainbow stripes could also relate to this, being an iconic gay symbol.
