Aldo Tessio

Aldo Emilio Tessio (October 28, 1909 – January 17, 2000) was an Argentine politician belonging to the Radical Civic Union (UCR).

Born in Esperanza, Santa Fe, Tessio joined the centrist UCR as a student, and earned a Law Degree at the National University of the Littoral.

Governing one of the nation's most important provinces, his term was distinguished by its transparency, as well as its emphasis on public works: the Brigadier Estanislao López Highway, one of Argentina's first intercity freeways, was built, as were numerous housing projects, much of the east–west provincial road infrastructure, and other works.

His term was prematurely ended by the 1966 coup d'état that ousted president Arturo Illia and brought to power the military dictatorship led by Juan Carlos Onganía.

The Justicialist Party Governor Jorge Obeid spoke of him in eulogy as "an illustrious character of Argentine democracy," noting his commitment to human rights; in recognition for his efforts to improve Santa Fe's infrastructure, a segment of Provincial Route 13 was renamed after him by Obeid on the 41st anniversary of Tessio's inaugural as governor.
