Hipólito Yrigoyen, Argentinian educator and politician, 19th President of Argentina (born 1852)

Juan Hipólito del Sagrado Corazón de Jesús Yrigoyen was an Argentine politician of the Radical Civic Union who served as President of Argentina from 1916 to 1922 and again from 1928 until his overthrow in 1930. He was the first president elected democratically by means of the secret and mandatory male suffrage established by the Sáenz Peña Law of 1912. His activism was the prime impetus behind the passage of that law in Argentina.

The president of Argentina, officially known as the president of the Argentine Nation, is both head of state and head of government of Argentina. Under the national constitution, the president is also the chief executive of the federal government and commander-in-chief of the armed forces.
