Robert Tappan Morris (born November 8, 1965) is an American computer scientist and entrepreneur. He is best known for creating the Morris worm in 1988, considered the first computer worm on the Internet, and for being the first person convicted under the Computer Fraud and Abuse Act (CFAA). He later cofounded the online store Viaweb and the venture capital funding firm Y Combinator, and became a tenured professor at the Massachusetts Institute of Technology (MIT).

Lore & Background
Morris was born in 1965 to Robert Morris and Anne Farlow Morris. His father was a computer scientist at Bell Labs who helped design Multics and Unix, and later became chief scientist at the National Computer Security Center, a division of the NSA. Morris grew up in Millington, New Jersey, attended The Peck School, and graduated from Delbarton School in 1983. He attended Harvard University and later graduate school at Cornell University.
During his first year of graduate school at Cornell in 1988, Morris developed the Morris worm, which he released from MIT to avoid tracing. The worm exploited vulnerabilities in sendmail, fingerd, and rexec/rsh. A design flaw caused the worm to copy itself 14% of the time even if infection was detected, creating system loads that disrupted target computers. Estimated economic impact ranged up to $10,000,000.
In 1989, Morris was indicted under the CFAA, the first person so charged. In December 1990, he was sentenced to three years of probation, 400 hours of community service, and a fine of $10,050 plus supervision costs. His conviction was affirmed on appeal. He completed his sentence as of 1994. Morris stated his motive was 'to demonstrate the inadequacies of current security measures on computer networks.'
Reader's Guide
Robert Tappan Morris occupies a unique place in computing history as both a pioneering hacker and a respected academic and entrepreneur. His 1988 worm, though intended as an experiment, inadvertently caused widespread disruption and led to his landmark conviction under the CFAA, shaping early internet security law. Despite this, Morris transitioned to a successful career: cofounding Viaweb, one of the first web applications, and later Y Combinator, a major startup accelerator. He earned a Ph.D. from Harvard, became a tenured professor at MIT, and was elected to the National Academy of Engineering in 2019. His research in computer network architectures, including distributed hash tables and wireless mesh networks, has influenced the field. Morris's trajectory from convicted hacker to academic and tech leader illustrates the complex interplay between innovation, security, and legal boundaries in the digital age.

Frequently Asked Questions
Who is Robert Tappan Morris?
Robert Tappan Morris is an American computer scientist and entrepreneur, born November 8, 1965, best known for writing the first Internet worm in 1988. He later became a successful tech founder and earned a tenured professorship at MIT.
What was the Morris worm and why does it matter?
Released in 1988, the Morris worm was the first self-replicating program to propagate across the early Internet, infecting roughly ten percent of connected machines. It fundamentally reshaped how the world approached network security and spurred the creation of dedicated cybersecurity disciplines.
What were the legal consequences for Morris after the worm?
He became the first individual ever convicted under the United States Computer Fraud and Abuse Act. His case established a landmark precedent for prosecuting unauthorized access to computer systems.
What did Morris do after his conviction?
He pivoted into the startup world, co-founding the online storefront platform Viaweb (later acquired by eBay) and the venture capital firm Y Combinator, which has backed numerous high-profile tech companies. He also pursued academia, ultimately securing a tenured position at MIT.
Why is Robert Tappan Morris considered a unique figure in tech history?
He holds the rare distinction of being both the author of the first major Internet security threat and a highly successful entrepreneur who helped shape the modern startup ecosystem. His arc from convicted hacker to MIT professor and Y Combinator co-founder makes him one of computing's most unconventional figures.
