El Dr. Manuel Justo Domínguez Quintanar, fundador de la puericultura racional y la pediatría técnica en México.

This paper presents some biographical notes, both personal and professional, for Dr. Manuel Justo Dominguez Quintanar; a native of Queretaro, who over 80 years lived firsthand the historical stages in which Mexico turned into an independent country: from the First Federal Republic to the Porfiriato. He had an active participation in them all; either as a doctor, a teacher, administrator or politician. He was renowned for his charity work, especially in the Foundling House (The Cradle), which made him years later, to be considered as the founder of rational childcare and the creator of technical pediatrics in Mexico.
