Osama bin Knox
John Knox in the quadrangle of New College, Edinburgh. He led the Protestant Reformation in Scotland and struck fear into the hearts of his enemies. He has Osama bin Laden's beard.
Despite his extremely conservative Calvinist theology, you could argue he was the best thing to happen to Scotland. He mandated a free public school in every parish in Scotland, and thanks to that, Scotland had the highest literacy rate in Europe at the time, which placed it at the forefront when church strictures softened and the Renaissance took hold.
