Greek shipping magnate and international businessman. Born in Smyrna, Greece (now Turkey), the son of a tobacco dealer, he started a tobacco-importing business in Buenos Aires. He was made consul general after negotiating a trade agreement for the Greek government. A millionaire by age 25, he bought his first freight ships in 1932. In the 1940s and '50s his fleet grew until it was larger than the navies of many countries. He acquired business interests in Monte Carlo, and from 1957 to 1974 owned and operated Olympic Airways, the Greek national airline. He conducted a long affair with M. Callas, and in 1968 married Jacqueline Kennedy (see J. K. Onassis).
