The perpetrator of the great Internet worm of 1988 (see GreatWorm); villain to many, naive hacker gone wrong to a few.

Morris claimed that the worm that brought the Internet to its

knees was a benign experiment that got out of control as the

result of a coding error. After the storm of negative

publicity that followed this blunder, Morris's user name on ITS

was hacked from RTM to RTFM.
