클럽 아틀레티코 아틀란타

The club was founded on 12 October 1904 in Buenos Aires, Argentina. One source says that the team got its name from an earthquake that had struck Atlanta, Georgia in the United States at the time the founders got together to inaugurate the club. Another version about its foundation states that the name "Atlanta" was taken from a navy ship that had arrived in the port of Buenos Aires when Manuel Quintana was proclaimed as President of Argentina. Elias Sanz was named as the club's first president.^[]

The club's colors, yellow and blue, where chosen from the awnings that decorated the neighborhood's stores in those years. Atlanta's first home field was in Juan B. Alberdi y Escalada Avenue of the Villa Luro neighborhood, but the club would move repeatedly. This constant movement is the reason why the club was nicknamed Los Bohemios, the Bohemians, which has remained the nickname for the club and its supporters.^[]
