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 Almánzar. 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.
Diplomat
In 1931, Rubirosa met Rafael Trujillo at a country club. The "Benefactor" asked to see him the next morning, and made him a lieutenant of his Presidential Guard. Their relationship lasted throughout their lives, went up and down, mostly close, but not without episodes of danger for Rubirosa, and defined his professional career when he became a diplomat of the Dominican Republic in 1936. In this role, he was sent to embassies, first at Berlin and soon to Paris, where he spent most of his time; he also served at the embassies at Vichy, Buenos Aires, Rome, Havana, and Brussels. He was a frequent visitor to New York, Washington, Florida, and California. "Rubi", who defined himself a Trujillista, moved freely among the rich and famous, made the connections, and kept the secrets. His 1938 divorce of Trujillo's daughter seemed, at least on the surface, to have little influence over his erstwhile father-in-law's affection for, or trust in, him. However, at times, when his escapades stirred up too much notoriety, Trujillo would dismiss him - as from his post in Paris in 1953 - or move him to another place. Trujillo recognized what an asset Rubirosa was for his regime, remarking: "He is good at his job, because women like him and he is a wonderful liar." After Trujillo's assassination on May 30, 1961, Rubirosa supported his son as successor and attempted to persuade John F. Kennedy to help his government. When Ramfis Trujillo and his family fled the Dominican Republic, Rubirosa's career came to an end. On January 2, 1962, the Council of State removed him from his unique appointment as "Inspector of Embassies". After he lost his diplomatic immunity, he was questioned by the New York District Attorney concerning the disappearance of Trujillo opponents Sergio Bencosme in 1935 and Jesus Galíndez in 1956, but was never charged.

His playboy lifestyle was matched by stories of his sexual prowess. His reputedly larger than average penis size inspired Parisian waiters at Maxim's to name gigantic pepper mills "Rubirosas". The name stuck and has been in use all over the world.
After World War II, Rubirosa became engaged in two major passions, polo and car racing, both expensive sports that would be supported in years to come by his wives. He organized and led his own polo team Cibao-La Pampa that was an often successful contender for the Coupe de France. Rubirosa played polo until the end of his life. In the same period, he started to acquire fast cars and form friendships with racing car drivers. He would own a number of Ferraris. His first race at 24 Hours of Le Mans took place in June 1950 with his partner Pierre Leygonie, and his second race, this time with Innocente Baggio, was four years later; in both races his car did not finish. Rubirosa participated in a number of races at Sebring, all but once as a private entry. Rubirosa entered one Formula One race, in 1955, the Grand Prix de Bordeaux on April 25. He planned to drive his own Ferrari 500, identical to the one which brought Alberto Ascari the and Drivers' World Championship. However, he fell ill before the race and did not drive.
Death
Rubirosa died in the early morning of July 5, 1965, at the age of 56, when he crashed his silver Ferrari 250 GT cabriolet into a horse chestnut tree in the Bois de Boulogne after an all-night celebration at the Paris nightclub "Jimmy's" in honor of winning the polo Coupe de France.
