Although Gandhi is best known for expelling the British from India and inspiring the likes of King and Mandela, he also wrote a lot about the behavior of good business leaders.

Several outstanding women were nominated, but Rainbow Murray, an adviser to the series, says the public vote showed how we're still more inclined to recognise male achievement.
Howard Thurman, a mentor to MLK, first met Gandhi during a visit to India in 1936. He came to understand nonviolence as a force more powerful than hate that had the power to transform the world.
Thurman was 30 years older than King: the same age, in fact, as King's father. Among his most significant contributions was bringing the ideas of nonviolence to the civil rights movement.
At times we just don't know what's the right thing to do. St. Ignatius, who founded the Society of Jesus, developed a method of discernment that can be useful even to those who are not religious.
