Jeff Bezos

A former Amazon executive who helped Jeff Bezos turn shopping into a digital experience has set out to end illiteracy. David Risher is now the head of Worldreader, a nonprofit organization that brings e-books to kids in developing countries through Kindles and cellphones.

Risher was traveling around the world with his family when he got the idea for Worldreader. They were doing volunteer work at an orphanage in Ecuador when he saw a building with a big padlock on the door. He asked a woman who worked there what was inside, and she said, "It's the library."

The daily lowdown on books, publishing, and the occasional author behaving badly.
