My nominee for the post, and I’m far from alone in saying this, is Brewster Kahle. (Disclosure: He’s a friend.) For the past two decades he’s led one of the genuine treasures of our age, as founder and director—he calls himself “digital librarian”—of the Internet Archive. A graduate of the Massachusetts Institute of Technology, he’s been a founder or co-founder of some of the most path-breaking technology projects in recent times, including the Wide Area Information Server, an early Internet publishing system, and the Alexa Internet catalog system, which he sold to Amazon in the 1990s. His biography is amazing, and his commitment to the public good is inspiring. —Brewster Kahle, creator of the Internet Archive, should be the next Librarian of Congress.
