Brewster Kahle

In 1996 Brewster Kahle, a computer engineer and internet entrepreneur, cofounded Alexa Internet—which compiles data on website traffic and user behavior—before selling it to Amazon in 1999. He is also a cofounder and the digital librarian of the Internet Archive, which now preserves forty-five petabytes of data. “Brewster is one of those guys who has been successful in spite of the fact that he has never been after that kind of success,” wrote computer scientist Kip Parent. “He’s been pushing protocols for the benefit of humanity.”
