Rafael Caldera

Rafael Antonio Caldera Rodríguez ( ; 24 January 1916 – 24 December 2009), was a Venezuelan politician and academician who was the president of Venezuela for two five-year terms (1969–1974 and 1994–1999), becoming the longest serving democratically elected leader to govern the country in the twentieth century. His first term marked the first peaceful transfer of power to the opposition in Venezuela's history. Widely acknowledged as one of the founders of Venezuela's democratic system, one of the main architects of the 1961 Constitution, and a pioneer of the Christian Democratic movement in Latin America, Caldera helped forge an unprecedented period of civilian democratic rule in a country beleaguered by a history of political violence and military caudillos.

His leadership established Venezuela's reputation as one of the more stable democracies in Latin America during the second half of the twentieth century.

After graduating with a degree in law and political science from Central University of Venezuela in 1939, Caldera embarked on a 70-year-long career that combined political, intellectual and academic activities. Provided by Wikipedia
