(Buenos Aires 1860 / 1901)
He was born in Buenos Aires on February 22, 1860, son of the Spanish couple Toribio Ayerza and Adelaida Zabala. He studied at Colegio Del Salvador and graduated as a lawyer from the University of Buenos Aires at the age of twenty. He was a well known lawyer, and occupied a seat in the Chamber of Deputies of the Nation (1894). He had a great interest in photography. On April 29, 1889, in the city of Buenos Aires, he founded, along with a group of friends, the Sociedad Fotográfica Argentina de Aficionados (SFA de A), which functioned until 1926. On the day of its foundation in Ayerza's house, located in Piedad 1266, its provisional commission was made up of President: Francisco Ayerza, Vice President: Germán Ruhr, Members: José María Gutiérrez, Roberto Wernicke, Ricardo N. Murray, Fritz Büsch, Juan D. Quevedo and Isidro Calderón y Piñeyro. Also present were Daniel Mackinlay, Fernando Steinius, Fernando Denis and Leonardo Pereyra Iraola.
Yesterday, who died of syncope at the early age of 41, he produced one of the first photographic works of fiction in Argentina: José Hernández's interpretation of Martín Fierro's Gaucho. For this work (incomplete, since Ayerza abandoned the ambitious project) he used as a model the workers of the San Juan de Pereyra Iraola ranch, today in lands near the current park with the same name, next to the city of La Plata. The Martín Fierro de Ayerza was made with a huge bellows camera and wooden tripod, with glass negatives 24 x 30 cm. This large format gave the images that make up the set an extraordinary technical quality.
