Barton Miller describes coining the term.

   ‘That night, I was logged on to the Unix system in my office via
    a dial-up phone line over a 1200 baud modem.  ...
    I wanted a name that would evoke the feeling of random, unstructured
    data.  After trying out several ideas, I settled on the term “fuzz”.’

Line noise inspired him, as he describes.
