Robert Melancton Metcalfe (born April 7, 1946) is an engineer and entrepreneur from the United States who helped pioneer the Internet starting in 1970. He co-invented Ethernet, co-founded 3Com and formulated Metcalfe's law, which describes the effect of a telecommunications network. Since January 2011, he has been Professor of Innovation and Entrepreneurship at The University of Texas at Austin. He is also the Murchison Fellow of Free Enterprise.

In addition to his accomplishments, Metcalfe has made several predictions which failed to come to pass, separately forecasting the demise of the Internet, wireless networks, and open-source software during the 1990s.
Robert Metcalfe was born in 1946 in Brooklyn, New York. His father was a gyroscope test technician, who specialized in gyroscopes. His mother was a homemaker but later became the secretary at Bay Shore High School. In 1964, Metcalfe graduated from Bay Shore High School to join the MIT Class of 1968. He finally graduated from MIT in 1969 with two S.B. degrees, one in electrical engineering and the other in industrial management from the MIT Sloan School of Management. He then went to Harvard for graduate school, earning his M.S. in applied mathematics in 1970 and his PhD in computer science (applied mathematics) in 1973.
While pursuing a doctorate in computer science, Metcalfe took a job with MIT's Project MAC after Harvard refused to let him be responsible for connecting the school to the brand-new ARPAnet. At MAC, Metcalfe was responsible for building some of the hardware that would link MIT's minicomputers with the ARPAnet. ARPAnet was initially the topic of his doctoral dissertation, but the first version was not accepted. His inspiration for a new dissertation came while working at Xerox PARC, where he read a paper about the ALOHA network at the University of Hawaii. He identified and fixed some of the bugs in the AlohaNet model and made his analysis part of a revised thesis, which finally earned him his Harvard PhD in 1973.
Metcalfe was working at PARC in 1973 when he and David Boggs invented Ethernet, initially a standard for connecting computers over short distances. Metcalfe identifies the day Ethernet was born as May 22, 1973, the day he circulated a memo titled "Alto Ethernet" which contained a rough schematic of how it would work. "That is the first time Ethernet appears as a word, as does the idea of using coax as 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 identifies another date as the birth of Ethernet: November 11, 1973, the first day the system actually functioned.
In 1979, Metcalfe departed PARC and co-founded 3Com, a manufacturer of computer networking equipment, in his Palo Alto apartment. In 1980 he received the ACM Grace Hopper Award for his contributions to the development of local networks, specifically Ethernet. In 1990, in a boardroom skirmish, the 3Com board of directors chose Eric Benhamou to succeed Bill Krause as CEO of the networking company instead of Metcalfe. Metcalfe left 3Com and began a 10-year stint as a publisher and pundit, writing an Internet column for InfoWorld. He became a venture capitalist in 2001 and is now a general partner at Polaris Venture Partners. In 1997, he co-founded Pop!Tech, an executive technology conference.
In 2003 he received the Marconi Award for "For inventing the Ethernet and promulgating his Law of network utility based on the square of the nodes"
On March 14, 2003, Metcalfe received the National Medal of Technology from President Bush in a White House ceremony "for leadership in the invention, standardization, and commercialization of Ethernet".
Metcalfe predicted in 1995 that the Internet would suffer a "catastrophic collapse" 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. He had tried to eat his words printed on a very large cake, but the audience would not accept this form of "eating his words."
During an event where he talked about predictions at the eighth International World Wide Web Conference in 1999, a participant asked: what is the bet?. He stated that there was no bet as he was not ready to eat another column.
- The Open Source Movement's ideology is utopian balderdash [... that] reminds me of communism. [...] Linux [is like] organic software grown in utopia by spiritualists [...] When they bring organic fruit to market, you pay extra for small apples with open sores – the Open Sores Movement. When [Windows 2000] gets here, goodbye Linux.
He later recanted to some extent, saying in a column two weeks later:
- I am ashamed of myself for not resisting the temptation to take cheap shots in my column ... I should not have fanned the flames by joking about the Open Source initiative.
He predicted that wireless networking would die out in the mid 1990s.:
- After the wireless mobile bubble bursts this year, we will get back to stringing fibers ... bathrooms are still predominantly plumbed. For more or less the same reason, computers will stay wired.
He predicted in 2006 that Windows and Linux would not be able to handle video:
- Bob Metcalfe recently gave a TV interview in which he stated that current operating systems (Windows and Linux) are outdated clunkers that won't be able to adequately handle the coming of "video internet" and suggests that new operating systems need to be developed to take hold in a few years.
