Argentine statesman who was his country's president in 1895–98.

Born into an old aristocratic family, Uriburu earned his doctoral degree in law in 1854 and then entered public life. He served in various government positions and held important diplomatic posts in several South American countries. He became Argentina's minister to Chile in 1883, and in that office he helped mediate the dispute at the end of the War of the Pacific, which Chile had waged against Bolivia and Peru. In 1892 Uriburu was elected vice president of Argentina, and he succeeded to the presidency after Luis Sáenz Peña resigned in January 1895. During his term Uriburu reorganized the armed forces and made reforms in public finance so that Argentina could resume payment on the public debt. He also continued peaceful relations with Chile during the serious boundary dispute with that country. He retired from the presidency in 1898, but served as interim president in 1903. From 1901 to 1910 he was a senator in the National Congress. His son, José Evaristo Uriburu (1880–1956), served as minister (1921–27) and ambassador (1927–31) to Great Britain; his nephew, José Félix Uriburu (Uriburu, José Félix), seized power in a conservative coup in 1930.
