Enrico Martínez, also known as Henri Martín or Heinrich Martin, was a prominent cosmographer, publisher, and hydraulic engineer. His noteworthy contribution includes serving as the cosmographer to the King of Spain and working on draining the valley surrounding Mexico City in the early 17th century. Martínez was tasked with the challenging project of preventing the overflow of the Lakes of Zumpango and San Cristóbal into the basin, which posed a significant threat to the city. Despite facing challenges such as corrosion and financial constraints, Martínez diligently worked on the canal, known as Huehuetoca or Nochistongo, aimed at averting the danger of inundations. However, his efforts faced criticism and disputes, leading to the eventual arrest and imprisonment of Martínez. Despite subsequent attempts to rectify the situation, including the involvement of other engineers, the project ultimately experienced further setbacks, and the tunnel Martínez worked on was eventually converted into an open canal in 1789. Martínez also authored several published works, including "Lunario y Regimiento de Salud" and "Repertorio de tiempo e historia natural de Nueva Espana." His legacy continues to be associated with his significant contributions to hydraulic engineering and his written works on various subjects related to New Spain.
