Robert T. Morris is a professor at M.I.T. and founding partner of Y Combinator.  Prior to those, he co-founded Viaweb and created the RTML markup language used by Yahoo! Store.  Robert T. Morris was also the first person held accountable under the Computer Fraud and Abuse Act of 1986.  In 1988, at the age of 23, Mr. Morris released the so-called “Morris Worm” to gauge the Internet’s size that ultimately affected 6,000 computers.

Business Insider has an interesting article about how Robert Morris’ acts in 1988 relate to Aaron Swartz’ alleged acts.  The article also explains how the controversy surrounding the Swartz case has resulted in calls for reform of the federal anti-hacking laws, the so-called “Aaron’s Law” proposal.
