I know five...

I would be interested to learn about pacifists. Are there any famous ones?

Top 5 most famous pacifists (according to Pandora):

1. Siddhartha Gautama (Buddha) - founder of Buddhism, which became the historical origin of this movement

2,3. John Lennon and Yoko Ono (his wife) - "Bed-In for Peace" (a political action against the war in Vietnam and for peace throughout the world) + the song "Give Peace a Chance" (became an anthem of the pacifist movement)

4,5. Albert Einstein and Nikola Tesla actively spoke out against war and oppression

Five most distinctive features (symbols) of the 60s, right? :)
