Stavros Niarchos, Greek shipping magnate (d.1996)
Stavros Spyrou Niarchos (Greek: Σταύρος Σπύρου Νιάρχος, pronounced [ˈstavros ˈspiru 'ɲarxos]; 3 July 1909 – 15 April 1996) was a Greek billionaire shipping tycoon. Starting in 1952, he had the world's biggest supertankers built for his fleet. Propelled by both the Suez Crisis and increasing demand for oil, he and rival Aristotle Onassis became giants in global petroleum shipping.

Niarchos was also a noted thoroughbred horse breeder and racer, several times the leading owner and number one on the French breed list.
