The CND or Peace symbol
This forked symbol was adopted as its badge by the Campaign for Nuclear Disarmament in Britain, and originally, its use was confined to supporters of that organization. It was later generalised to become an icon of the 1960s anti-war movement, and was also adopted by the counterculture of the time. It was designed and completed February 21, 1958 by Gerald Holtom, a commercial designer and artist in Britain. He had been commissioned by the CND to design a symbol for use at an Easter march to Canterbury Cathedral in protest against the Atomic Weapons Research Establishment at Aldermaston in England.
The symbol itself is a combination of the semaphoric signals for the letters "N" and "D," standing for Nuclear Disarmament. In semaphore the letter "N" is formed by a person holding two flags in an upside-down "V," and the letter "D" is formed by holding one flag pointed straight up and the other pointed straight down. These two signals imposed over each other form the shape of the peace symbol. In the original design the lines widened at the edge of the circle.
A conscientious objector who had worked on a farm in Norfolk during the Second World War, Holtom later wrote to Hugh Brock, editor of Peace News, explaining the genesis of his idea in greater depth: "I was in despair. Deep despair. I drew myself: the representative of an individual in despair, with hands palm outstretched outwards and downwards in the manner of Goya's peasant before the firing squad. I formalised the drawing into a line and put a circle round it." He also mentioned that he had intended its obvious resemblance to the anarchy symbol.
However, it is more commonly believed that Holtom merely put a circle around a symbol that appeared throughout the English countryside near airbases. That symbol was of a strategic bomber which could be seen on road signs indicating where the air fields were located. This is a much less creative and emotional explanation for the symbol.
The peace symbol flag first became known in the United States in 1958 when Albert Bigelow, a pacifist protester, sailed his small boat outfitted with the CND banner into the vicinity of a nuclear test. The peace symbol button was imported into the United States in 1960 by Philip Altbach, a freshman at the University of Chicago, who traveled to England to meet with British peace groups as a delegate from the Student Peace Union (SPU). Altbach purchased a bag of the "chickentrack" buttons while he was in England, and brought them back to Chicago, where he convinced SPU to reprint the button and adopt it as its symbol. Over the next four years, SPU reproduced and sold thousands of the buttons on college campuses.
In Unicode, the peace symbol is U+262E, and can thus be generated in HTML by typing ☮ or ☮. However, many browsers will not have a font that can display it.
