Bob Metcalfe, engineer, technology executive and venture capitalist, invented the Ethernet.

Bob Metcalfe - inventor of Ethernet

It's hard to guess just what Robert Metcalfe might be up to in a given year. From inventing Ethernet, the networking system which allowed personal computers to communicate with each other in the 1970s, he went on to found the multibillion-dollar company 3Com, then later quit to become a technology pundit. These days, when not writing his nationally syndicated InfoWorld column or making brash predictions about the future of the Net at industry conferences, you might find him with his wife, Robyn, tending to 200-pound rare pigs on the couple's 450-acre Kelmscott Farms in Maine.
