Porfirio Rubirosa Ariza (January 22, 1909 – July 5, 1965) was a Dominican diplomat, race car driver, soldier and polo player. He was an adherent of the dictator Rafael Trujillo, and was also rumored to be a political assassin under his regime. Rubirosa made his mark as an international playboy for his jetsetting lifestyle and his legendary sexual prowess with women. Among his spouses were two of the richest women in the world.
Porfirio Rubirosa Ariza was born in San Francisco de Macorís, Dominican Republic, the third and youngest child of an upper-middle-class family. His parents were Pedro María Rubirosa and Ana Ariza Almanzar. The eldest child was named Ana and the elder son was named César. His father, also a womanizer, was at one time a "general" of a group of heavily armed men in the mountainous Cibao region working with the government. Don Pedro advanced to become a diplomat, and after a stint at St. Thomas was made Chief of the Dominican Embassy to Paris in 1915. Rubirosa thus grew up in Paris, France and returned to the Dominican Republic at the age of 17 to study law. But he soon changed course and enlisted in the military.
