There's such a mixture of triumph and tragedy in the story of Danny Lewin.
The triumph came with computers: he figured out ways to make the Internet faster. The tragedy came in his early death: Lewin was 31 when he boarded one of the planes that ended up crashing into the World Trade Center on September 11, 2001.
Lewin's story is told in No Better Time: The Brief, Remarkable Life of Danny Lewin, the Genius Who Transformed the Internet. Author Molly Raskin joins us.
