Rodríguez Lozano was born to Manuel
Rodríguez and his wife Sara Lozano. He began a military
education at the Heroico Colegio Militar, and started a
diplomatic service career. In Spain, he met Carmen Mondragón,
daughter of general Manuel Mondragón, whom he married on August
13, 1913.
They traveled to Paris, where they got contact to the
avant-garde movement there, met Henri Matisse, Georges Braque,
Pablo Picasso, André Lhote, André Salmon and Jean Cassou,
between others. Afterwards they moved to San Sebastián, Spain,
where they autodidactically trained painting.
During the
seven-year stay in Europe, their son died, reportedly due to a
fury attack of Carmen Mondragón. His death was probably the
cause of their separation, although other possible causes are
Rodríguez-Lozano's bisexuality or Carmen Mondragón's
nymphomaniac tendencies. It is unknown whether or not they ever
officially separated.
In 1921 both returned to Mexico, where
Carmen Mondragón met Gerald Murillo aka Dr Atl, who gave her the
name "Nahui Ollin"
