When Larry Landweber was growing up in Brooklyn, N.Y., in the 1950s, he competed on his high school math team. But he never imagined he would become a leader in a technology that has dramatically changed the world. Yet Landweber, 69, the John P. Morgridge professor emeritus of computer science at UW-Madison, is one of 33 people from nine countries who were the first to be inducted into the Internet Hall of Fame last April in Geneva.
