The number of hospital beds in Argentina grew from 66,300 in 1946 to 132,000 by 1954 under the direction of Ramón Carrillo. A neurosurgeon and scientist who pivoted toward structural public health reform, he sought to address the systemic inequalities he witnessed during his tenure as the nation's inaugural Minister of Public Health.
Academic and Scientific Foundation
Born in 1906 in Santiago del Estero, Carrillo excelled at the Faculty of Medical Sciences at the University of Buenos Aires, graduating in 1929 with a Gold Medal. He pursued advanced neurological studies in Europe with researchers Cornelius Ariëns Kappers and Carl Vogt. Upon returning to Argentina, he built a robust scientific portfolio, contributing to the understanding of glial cells and refining iodoventriculography. In 1942, he secured the Chair of Neurosurgery at the University of Buenos Aires, training numerous prominent physicians while developing early diagnostic precursors to modern tomography.

His service as the Head of the Neurology and Neurosurgery Service at the Central Military Hospital beginning in 1939 exposed him to the poor state of rural medical infrastructure. By analyzing health data from military recruits, he identified that nearly half of the country lacked access to essential medical facilities. His eventual collaboration with Juan Domingo Perón moved him from the laboratory into the political arena, where he served briefly as Dean of the School of Medicine before joining the national administration.
Ministerial Tenure and Infrastructure
Appointed head of the State Secretary of Public Health in 1946, he became the first Minister of Public Health in 1949. Alongside figures like Salomón Chichilnisky and his brother Santiago Carrillo, he focused on rapid expansion of the healthcare network. Working with the Eva Perón Foundation, he oversaw the construction of 234 public hospitals. These efforts significantly reduced mortality rates, specifically slashing tuberculosis deaths and eliminating malaria through aggressive anti-vector campaigns.
