a party with the possibility of accessing power. But, suddenly, the UCR reappeared showing a political and territorial organization far superior to that of the ruling party, and a great revolutionary decision, in the radical revolution of 1905, in which several units of the Army were involved. Exploded on February 4 of that year, it was relatively successful in Buenos Aires, Rosario, Córdoba, Bahía Blanca and Mendoza, but was quickly put down. Attempt on his life On August 11, 1905, Quintana and his wife, Susana Rodríguez Viana, suffered an attack against their lives, when Salvador Planas y Virella, a Catalan anarchist, shot at the presidential vehicle, but he could not carry out his task due to a failure in the pistol he used. Planas declared that he acted alone and that his motivation was to avenge the workers killed during the demonstration on May 21 of that year. He was arrested and during the trial in September 1907 the defense alleged mental instability. Planas was sentenced to 10 years in prison for attempted murder. On January 6, 1911, he fled the Buenos Aires National Penitentiary with the anarchist Francisco Solano Regis, who had attacked President José Figueroa Alcorta, Quintana's successor. Health and death The stress suffered by the president during the revolution and the subsequent attempt on his life damaged his health. As a consequence, he reduced his working hours to a minimum, which complicated his administration. Despite all attempts, Quintana's health continued to deteriorate, so on January 25, 1906, Quintana decided to take a license, delegating the position on an interim basis to Vice President Figueroa Alcorta. Quintana retired to a farm in the current Belgrano neighborhood, to rest and try to improve his health. However, Quintana was already very old, and finally died on March 12, 1906, becoming the first Argentine president to die in office. His remains rest in the Recoleta Cemetery. Legacy Quintana's portrait was featured on the five hundred thousand austral banknote that circulated during the hyperinflation in Argentina from 1989 to 1991.
