Robert Capa photographed Spanish Civil War scenes from 1936 to 1939. In 1936 he gained worldwide recognition for a photo he took on the Córdoba Front of a loyalist militiaman as he fell after being shot. Often referred to as The Death of a Loyalist Soldier (a.k.a. Loyalist Militiaman at the Moment of Death, Cerro Muriano, September 5, 1936), the photograph became the best-known picture of the Spanish civil war, but it was not without controversy. Critics have long questioned the photograph's authenticity, despite one historian's identification of the soldier as Federico Borrell García.
