Bob Metcalfe (co-invented Ethernet, founded 3Com and formulated Metcalfe’s Law) was born on April 7, 1946

Robert Melancton Metcalfe is an electrical engineer from the United States who co-invented Ethernet, founded 3Com and formulated Metcalfe’s Law. As of January 2006, he is a general partner of Polaris Venture Partners. Starting in January 2011, he holds the position of Professor of Electrical Engineering and Director of Innovation at The University of Texas at Austin. In 1964, Metcalfe graduated from Bay Shore Public High School. He graduated from MIT in 1969 with two B.S. 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 1970. 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 MIT’s Project MAC, Metcalfe was responsible for building some of the hardware that would link MIT’s minicomputers with the ARPAnet. Metcalfe was so enamored with ARPAnet, he made it the topic of his doctoral dissertation. However, Harvard flunked him. 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 Xerox PARC in 1973 when he and David Boggs invented Ethernet, 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 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 lost a boardroom skirmish at 3Com in the contest to succeed Bill Krause as CEO. The board of directors chose Eric Benhamou to run the networking company Metcalfe had founded in his Palo Alto apartment in 1979. 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. He is a director of Pop!Tech, an executive technology conference he cofounded in 1997. He has recently been working with Polaris-funded startup Ember to work on a new type of energy grid, Enernet.

Steve Jobs (American business magnate and inventor) was born on February 24, 1955

Steven Paul Jobs is an American business magnate and inventor. He is the co-founder and chief executive officer of Apple Inc. Jobs also previously served as chief executive of Pixar Animation Studios; he became a member of the board of The Walt Disney Company in 2006, following the acquisition of Pixar by Disney. He was credited in the 1995 movie Toy Story as an executive producer. In the late 1970s, Jobs, with Apple co-founder Steve Wozniak, Mike Markkula, and others, designed, developed, and marketed one of the first commercially successful lines of personal computers, the Apple II series. In the early 1980s, Jobs was among the first to see the commercial potential of the mouse-driven graphical user interface which led to the creation of the Macintosh. After losing a power struggle with the board of directors in 1984, Jobs resigned from Apple and founded NeXT, a computer platform development company specializing in the higher education and business markets. Apple’s subsequent 1996 buyout of NeXT brought Jobs back to the company he co-founded, and he has served as its CEO since 1997. In 1986, he acquired the computer graphics division of Lucasfilm Ltd which was spun off as Pixar Animation Studios. He remained CEO and majority shareholder at 50.1% until its acquisition by The Walt Disney company in 2006. Consequently Jobs became Disney’s largest individual shareholder at 7% and a member of Disney’s Board of Directors. Jobs’ history in business has contributed much to the symbolic image of the idiosyncratic, individualistic Silicon Valley entrepreneur, emphasizing the importance of design and understanding the crucial role aesthetics play in public appeal. His work driving forward the development of products that are both functional and elegant has earned him a devoted following.

Ray Dolby (Inventor of Dolby Noise Reduction) was born on January 18, 1933

Ray Dolby is an American engineer and inventor of the noise reduction system known as Dolby NR. He was also a co-inventor of video tape recording while at Ampex. He is the founder of Dolby Laboratories. He is also a billionaire and a member of the Forbes 400 with an estimated net worth of $2.9 billion in 2008 although as of September 2012 it was estimated to have declined to $2.4 billion. As a teenager, in the decade following World War II, Dolby held part-time and summer jobs at Ampex in Redwood City, working with their first audio tape recorder in 1949. While at San Jose State University and later at Stanford University (interrupted by two years of Army service), he worked on early prototypes of video tape recorder technologies for Alexander M. Poniatoff and Charlie Ginsburg. As a non degree-holding “consultant”, Dolby played a key role in the effort that led Ampex to announce quadruplex videotape in April 1956. In 1957, Dolby received his B.S. in electrical engineering from Stanford. He subsequently won a Marshall Scholarship for a Ph.D. (1961) in physics from Cambridge University, where he was a Research Fellow at Pembroke College. After Cambridge, Dolby acted as a technical advisor to the United Nations in India, until 1965, when he returned to England, where he founded Dolby Laboratories. In that same year, 1965, he officially invented the Dolby Sound System, although his first U.S. patent was not filed until 1969, four years later.
