Biography:

Women Strike for Peace (WSP, also known as Women for Peace) is a United States women's peace activist group. In 1961, at the height of the Cold War, about 50,000 women brought together by Women Strike for Peace marched in 60 cities in the United States to demonstrate against nuclear weapons. It was the largest national women's peace protest of the 20th century.[1] About 1,500 women led by Dagmar Wilson gathered at the foot of the Washington Monument and President John F. Kennedy watched from a window at the White House. The protest helped "push the United States and the Soviet Union into signing a nuclear test-ban treaty two years later".
