BOSTON — Halfway around the world from Tahrir Square in Cairo, an aging American intellectual shuffles about his cluttered brick row house in a working-class neighborhood here. His name is Gene Sharp. Stoop-shouldered and white-haired at 83, he grows orchids, has yet to master the Internet and hardly seems like a dangerous man.

Gene Sharp, 83, is known for writing about nonviolence.
But for the world’s despots, his ideas can be fatal.
Few Americans have heard of Mr. Sharp. But for decades, his practical writings on nonviolent revolution — most notably “From Dictatorship to Democracy,” a 93-page guide to toppling autocrats, available for download in 24 languages — have inspired dissidents around the world, including in Burma, Bosnia, Estonia and Zimbabwe, and now Tunisia and Egypt.
