René Préval, Haitian agronomist and politician, 52nd President of Haiti (d. 2017)
René Garcia Préval (French pronunciation: ​[ʁəne pʁeval]; 17 January 1943 – 3 March 2017) was a Haitian politician and agronomist who served twice as President of Haiti; once from early 1996 to early 2001, and again from mid 2006 to mid 2011. He was also Prime Minister from early to late 1991.

Préval was the first elected head of state in Haitian history to peacefully receive power from a predecessor in office, the first since independence to serve a full term in office, the first to be elected to non-successive full terms in office, the first to peacefully hand over power, and the first former prime minister to be elected president.

Préval promoted privatization of government companies, agrarian reform, and investigations of human rights abuses. His presidencies were marked by domestic tumult and attempts at economic stabilization, with his latter term seeing the destruction brought by the 2010 Haiti earthquake.
