Norman Morrison, a 31-year-old Quaker, sets himself on fire in front of the river entrance to the Pentagon to protest the use of napalm in the Vietnam war.

Norman R. Morrison was an American anti-war activist. On November 2, 1965, Morrison doused himself in kerosene and set himself on fire below the office of Secretary of Defense Robert McNamara at the Pentagon to protest United States involvement in the Vietnam War, leading to his death. This action was inspired by photographs of Vietnamese children burned by napalm bombings, and may have been inspired by Thích Quảng Đức and other Buddhist monks, who burned themselves to death to protest the repression committed by the South Vietnam government of Catholic President Ngo Dinh Diem.

Quakers are people who belong to the Religious Society of Friends, a historically Protestant Christian set of denominations. Members refer to each other as Friends after John 15:14 in the Bible. Originally, others referred to them as Quakers because the founder of the movement, George Fox, told a judge to "quake before the authority of God".

The Pentagon is the headquarters building of the United States Department of Defense, in Arlington County, Virginia, across the Potomac River from Washington, D.C. The building was constructed on an accelerated schedule during World War II. As a symbol of the U.S. military, the phrase The Pentagon is often used as a metonym for the Department of Defense and its leadership.

Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical. The name is a portmanteau of two of the constituents of the original thickening and gelling agents: coprecipitated aluminium salts of naphthenic acid and palmitic acid. A team led by chemist Louis Fieser originally developed napalm for the US Chemical Warfare Service in 1942 in a secret laboratory at Harvard University. Of immediate first interest was its viability as an incendiary device to be used in American fire bombing campaigns during World War II; its potential to be coherently projected into a solid stream that would carry for distance resulted in widespread adoption in infantry and tank/boat mounted flamethrowers as well.
