    Robert "Bob" Melancton Metcalfe (born April 7, 1946)

    development of the internet in the 1970s. He co-invented Ethernet, co-founded 3Com, and formulated Metcalfe's law
    , which describes the effect of a telecommunications network. Metcalfe has also made several predictions which failed to come to pass, including forecasting the demise of the internet during the 1990s.

    Metcalfe has received various awards, including the IEEE Medal of Honor and National Medal of Technology and Innovation for his work developing Ethernet technology. In 2023, he received the Turing Award, the highest distinction in computer science.[4] From 2011 to 2021, he was professor of innovation and entrepreneurship at the University of Texas at Austin.[5]

    Early life and family

    Robert Metcalfe was born in 1946 in

    homemaker who later became a secretary at Bay Shore High School.[6] Metcalfe graduated from that school in 1964.[7][6]

    Metcalfe graduated from the Massachusetts Institute of Technology in 1969, receiving two Bachelor of Science degrees in electrical engineering and industrial management. He then attended Harvard University and received a Master of Science in applied mathematics in 1970 and a PhD in computer science in 1973.[3][8]

    Metcalfe and his wife Robyn have two children.[9]

    Career

    While pursuing his doctorate in computer science, Metcalfe took a job with MIT's

    University of Hawaii. He identified and fixed some of the bugs in the AlohaNet model, then added that work to his revised thesis. It was then accepted by Harvard, which granted his PhD.[11]

    Metcalfe was working at PARC in 1973 when he and

    ether, where the participating stations, like in AlohaNet or ARPAnet, would inject their packets of data, they'd travel around at megabits per second, there would be collisions, and retransmissions, and back-off," Metcalfe explained. Boggs argued that another date was the birth of Ethernet: November 11, 1973, the first day the system actually functioned.[9]

    In 1979, Metcalfe departed PARC and co-founded

    Polaris Venture Partners.[3]

    From 2011 to 2021, he was a professor at

    Computer Science and Artificial Intelligence Laboratory as a research affiliate and computational engineer, working with the MIT Julia Lab.[17]

    Awards

    In 1996, Metcalfe was awarded the

    Marconi Award for "For inventing the Ethernet and promulgating his Law of network utility based on the square of the nodes".[21]

    Metcalfe was inducted into the National Inventors Hall of Fame in 2007, for his work with Ethernet technology.[22] In 2008, he received the Fellow Award from the Computer History Museum "for fundamental contributions to the invention, standardization, and commercialization of Ethernet."[23]

    In March 2023, Metcalfe was awarded the 2022 Association for Computing Machinery's Turing Award for his contributions to the invention of Ethernet technology.[24][25]

    Predicted Internet collapse

    In 1995, Metcalfe argued that the Internet would suffer a "catastrophic collapse" in the following year; he promised to eat his words if it did not. During his keynote speech at the sixth International World Wide Web Conference in 1997, he took a printed copy of his column that predicted the collapse, put it in a blender with some liquid and then consumed the pulpy mass.[26][27] He had suggested having his words printed on a very large cake, but the audience would not accept this form of "eating his words."[28]
