Carrillo appointed leading figures in Argentine medicine such as Salomón Chichilnisky, the neuroscientist Braulio Moyano, and his own brother, Santiago Carrillo (who had worked extensively with Moyano at Borda Hospital), to administrative posts in the new Health Ministry. Longtime colleagues at the University of Buenos Aires, Chichilnisky and the new Health Minister had become close friends during the latter's illness in 1937, and as Secretary of Health in the early 1950s he helped Health Minister Carrillo commission hundreds of public hospitals in Argentina. Perón's wife, Evita, also contributed to his tenure by coordinating public health policy at the well-funded Eva Perón Foundation with Carrillo, helping advance and fund many of his works and initiatives.
