Club Social y Atlético Guillermo Brown, mostly known as Guillermo Brown or Brown de Puerto Madryn, is an Argentine sports club from Puerto Madryn in Chubut Province. The football team currently plays in the Primera B Nacional.
The club was named in honour of Guillermo Brown who was the Irish-born first admiral of Argentina in the mid 19th Century.
Brown finished at the top of their group in the 2006 Clausura for the Torneo Argentino A, but failed in the next stage, after being defeated by San Martín de Tucumán in the playoff series with scores of 0–3 and 2–2.
On May 19, 2012, Brown achieved its greatest professional achievement in football, managing a 2–2 draw at Estadio Monumental with a last minute goal from against a River Plate squad with notable players such as David Trezeguet, Fernando Cavenaghi, Lucas Ocampos, and Alejandro Dominguez.[1] [2]
