In 1958, Gerald Holtom conceived the iconic peace sign for the British Campaign for Nuclear Disarmament, ingeniously incorporating elements from semaphore signals: the central vertical line denoting "D" and the downward lines on either side representing "N", encapsulating the powerful plea for nuclear disarmament within a encompassing circle.
Holtom's profound vision also interpreted the symbol as a poignant reflection of human despair, portraying a figure with hands outstretched, set against the backdrop of Earth.
