Jorge Mateo Cuesta Porte-Petit (b. Córdoba, Veracruz, September 23, 1903 – d. Tlalpan, August 13, 1942) was a Mexican chemist, writer and editor.
Cuesta attended school in his hometown, before he did his studies at the Faculty of Chemistry of Universidad Nacional Autónoma de México (UNAM) until 1925.
When he finished his studies, he moved back to Córdoba for a short time.
In 1927, back in Mexico City, he met his later wife Guadalupe Marín, who was married to Diego Rivera at that time.
[1] Following a fit of madness that included an act of self-castration, Cuesta was hospitalized and would later hang himself using the bedsheets from the sanitarium where he was interred.
