Where does the peace symbol come from? It was designed in the 1950s by Gerald Holtom for the Nuclear Disarmament movement.
The logo combines the flag signals for the letters “N” and “D” (“Nuclear Disarmament”). “N” is formed by a person holding two flags in an upside-down “V” position. “D” is formed by holding one flag straight up and the other straight down.
As you can see the pattern of “N” and “D” are overlapped and then encircled to form the familiar peace symbol.
