Freemasonic roots of the Anarchist Symbol
The first recorded use of the A in a circle by anarchists was by the Federal Council of Spain of the International Workers Association.
This was set up by the freemason, Giuseppe Fanelli in 1868. It predates its adoption by anarchists as it was used as a symbol by freemasons.
According to George Woodcock, this symbol was not used by classical anarchists. In a series of photos of the Spanish Civil War taken by Gerda Taro a small A in a circle is visible chalked on the helmet of a militiaman.

The first documented use was by a small French group, Jeunesse Libertaire ("Libertarian Youth") in 1964. Circolo Sacco e Vanzetti, youth group from Milan, adopted it in and in 1968 it became popular through out Italy. From there it spread rapidly around the world.
