In 1936, he became known across the globe for a photo (known as the "Falling Soldier" photo) presumably taken in Cerro Muriano on the Cordoba Front of a Loyalist Militiaman who allegedly had just been shot and was in the act of falling to his death. There has been a long controversy about the authenticity of this photograph. A Spanish historian identified the dead soldier as Federico Borrell García, from Alcoi (Alicante). This identification has been disputed; in fact there is a second photograph showing another soldier falling exactly on the same spot.[4][5] According to the Spanish newspaper El Periodico, the photo was taken near the town of Espejo, at 10 kilometres from Cerro Muriano, proving that the photo was staged [6][7]. In 2009, a Spanish professor published a book titled Shadows of Photography, in which he alleged that the photograph could not have been taken where, when or how Capa and his backers have alleged.[8]
