Jose Rivera, Tim Sullivan

José Eustasio Rivera Salas was a Colombian lawyer and poet primarily known for his national epic The Vortex.

After a failed attempt to be elected for the senate, he was appointed Legal Secretary of the Colombo-Venezuelan Border Commission to determine the limits with Venezuela, there he had the opportunity to travel through the Colombian jungles, rivers, and mountains, giving him a first hand experience of the subjects he would later write. Disappointed with the lack of resources offered by his government for his trip, he abandoned the commission and continued travelling on his own.

In this venture he became familiar with life in the Colombian plains and with problems related to the extraction of rubber in the Amazon jungle, a matter that would be central in his major work, La vorágine (1924) (translated as The Vortex), now considered one of the most important novels in Latin American literary history.

After the success of his novel, he was elected, in 1925, as a member for the Investigative Commission for Exterior Relations and Colonization. He also published several articles in newspapers in Colombia. In these pieces, he criticized irregularities in government contracts, and denounced the abandonment of the rubber extraction areas of Colombia and the mistreatment of workers.
