(Redirected from Bob Metcalfe)

Robert Metcalfe (born 1946 in Brooklyn, New York) is an American technology pioneer who invented Ethernet, founded 3Com and formulated Metcalfe's Law.

Metcalfe was working at Xerox PARC in 1973 when he invented Ethernet, a standard for connecting computers over short distances. In 1979, Metcalfe departed PARC and founded 3Com, a manufacturer of computer networking equipment. In 1980 he received the Association for Computing Machinery Grace Murray Hopper Award for his contributions to the development of local networks, specifically Ethernet. In 1990 Metcalfe retired from 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.

He graduated from MIT with two Bachelor's degrees, one in electrical engineering and another in industrial management from MIT's Sloan School of Management. He earned his Ph.D. from Harvard University, with a thesis on packet switching (which was actually written while working at MIT's Project MAC).

Metcalfe received the National Medal of Technology from President Bush in a White House ceremony on March 14, 2005, "for leadership in the invention, standardization, and commercialization of Ethernet." In 2004, according to IDC, there were 200 million new Ethernet ports shipped worldwide.ca:Robert Metcalfe da:Robert Metcalfe es:Robert Metcalfe fr:Robert Metcalfe it:Robert Metcalfe de:Robert Metcalfe nl:Robert Metcalfe
