Alan Turing and Enigma Machine

In 1999, Time Magazine named Turing as one of the 100 Most Important People of the 20th century and stated: "The fact remains that everyone who taps at a keyboard, opening a spreadsheet or a word-processing program, is working on an incarnation of a Turing machine."

The logo of Apple Computer is often erroneously referred to as a tribute to Alan Turing, with the bite mark a reference to his death. Both the designer of the logo and the company deny that there is any homage to Turing in the design of the logo. Stephen Fry has recounted asking Steve Jobs whether the design was intentional, saying that Jobs' response was, "God, we wish it were."

The Queen then officially pronounced Turing pardoned in August 2014. The Queen's action is only the fourth royal pardon granted since the conclusion of World War II.
