Biography
Ayerza was the son of the Basque doctor, Toribio Ayerza. He was a fervent catholic, married to Adela Arning with whom he had 11 children. One of his sons was kidnapped and later killed by Juan Gallifi a local Sicilian gangster which caused a great public outcry.

He undertook his higher education in the Medical Faculty of Salvador College in 1872. In 1882 he was a visiting practitioner to the Hospital de Mujeres (Women’s Hospital) and in 1884 was an internal practitioner of the Hospital de Clínicas. In 1885 he completed his practical studies as an intern in this hospital where he presented his thesis titled “Clinical Observations” sponsored by Dr. Ignacio Pirovano. He achieved his doctorate with a Gold Medal in 1886.

Two years later Ayerza travelled to Paris, France, to develop his technique of neurological examination and cardiopulmonary auscultation. Professor Jaccoud introduced him to nosology and Cartesian logical analysis at the Hôpital de la Pitié. He also worked with Jean Martin Charcot and Joseph Babinski at the Hôpital de la Sâltpetrière, with Pierre Carl Edouard Potain at the Hôpital de la Charité.

On his return to Buenos Aires in 1897 Ayerza acquired the position of First Chair of Clinical Medicine in the Medical Faculty of the University of Buenos Aires, the highest teaching level, where his particular educational style quickly found him renown.
