According to https://theweek.com November 15, 2017, "The peace sign was created in 1958 by British graphic designer and Christian pacifist Gerald Holtom. Holtom was tasked with creating the banners and signs for a nuclear disarmament march in London, and he wanted a visual that would stick in the public's mind."
