About Jorge Tadeo Lozano
Lived 1771 – 1816 (aged 45). Jorge Tadeo Lozano was a Colombian politician, chemist, journalist and botanist.
Jorge Tadeo Lozano de Peralta, Viscount of Pastrana (January 30, 1771 – July 6, 1816) was a Neogranadine (now Colombian) scientist, journalist, and politician who presided over the Constituent College of Cundinamarca and was elected President of Cundinamarca in 1811.
Early life Born Jorge Tadeo Lozano de Peralta y González Manrique, he was the son of the Marqueses of San Jorge, Jorge Miguel Lozano de Peralta Varaés Maldonado de Mendoza y Olaya, and María González Manrique del Frago Bonis. He was born on January 30, 1771, in Santafé de Bogotá, the capital of Viceroyalty of New Granada, present day Colombia.
Lozano was the quintessential Renaissance man, belonging to one of the most prestigious and affluent families of the viceroyalty, and receiving a very extensive and profound education. He studied literature, philosophy, and medicine in the Our Lady of the Rosary University, then called the Colegio Mayor del Rosario. After finishing his studies he opted for a career in the military, and continued his studies in Spain as part of the Walloon Guards, where he fought for Spain against the French in the War of the Pyrenees. Tadeo served under the command of the Spanish General Luis Firmin de Carvajal, Conde de la Union, and rose among the ranks to obtain the rank of Captain in the Royal Spanish Army. After finishing his studies, and retiring from his military service, Tadeo traveled through Europe and lived for a while in Paris.
When Lozano returned to New Granada in 1797, he became an active member of the tertulias of Bogotá, including the tertulia of the Casino, which was directed by Antonio Nariño, and frequented by other prominent criollos like Francisco Antonio Zea and Manuel de Bernardo Alvarez.
Journalism In 1801, Lozano and his relative José Luis Azuola y Lozano, founded the newspaper Correo curioso, erudito, económico y mercantil de la ciudad de Santafé de Bogotá, the third newspaper in the viceroyalty and in the history of Colombia. This weekly publication ran between February 17, 1801, and December 29 of the same year, with a total of 46 publications.
Political life Lozano's first involvement in politics was 1799, when he was appointed Mayor of Bogotá by the Real Audiencia of Bogotá, he however did not last long in this office. On July 31, 1807, he was appointed Lieutenant Protector of the Indians, for the regions of Bosa, Fusagasugá and Usaquén. This campaign was only the product of a popular discontent with Tadeo, who was criticised by many criollos for his connections with Spain and his title of nobility.
Lozano finally resigned on September 19, 1811, letting Nariño assume office. Afterwards he retired from politics and focused himself to his studies and his personal affairs.
Death and legacy During the Reconquista of the New Granada, the Pacificador Pablo Morillo invaded Bogotá and ushered the Reign of Terror, the purging of the Independentists and their institutions. Morillo sought out Tadeo, for his involvement in Congress, in the revolutionary newspaper El anteojo, and the fact that he was President of Cundinamarca, made him a prime target of the reign of terror. He was persecuted, his possessions taken away, and was finally arrested and held for two months, which culminated in his execution by firing squad on July 6, 1816, in the Orchard of Jaime, now the Plaza de los Mártires in Bogotá.
Lozano is considered a martyr and a hero of the Revolution and Independence of Colombia. His contribution to science, in the areas of Zoology, Botany and expeditions helped cement the basis of science in the education of the country. The Jorge Tadeo Lozano University was founded in his honour.
Personal life
Upon his return to the New Granada, Tadeo fell in love with his niece, María Tadea Lozano e Isasi, daughter of his brother José María Lozano de Peralta, 2nd Marquess of San Jorge. He expressed his desired to marry her, but the Roman Catholic Church could not marry them because of their level of consanguinity; he requested a dispensation from the Archbishop of Bogotá, Baltazar Jaime Martínez Compañón, for which he paid on June 7, 1797, 2 thousand pesos to be used as grants for the education of the girls of the Enseñanza school, six hundred pesos for church decorations, including two religious paintings, and the construction of an aqueduct in Funza.
