Who is the author of the photograph known as "Death of a Loyalist Soldier"?

Federico García was a Spanish Republican and anarchist militiaman during the Spanish Civil War, commonly thought to be the subject in the famous Robert Capa photo The Falling Soldier (September 5, 1936). Picture Post, a pioneering photojournalism magazine published in the United Kingdom, had once described then twenty-five year old Capa as "the greatest war photographer in the world."
