It is just under 50 years since Jackie Kennedy married the shipping mogul Aristotle Onassis in a tiny chapel on the Greek island of Skorpios.

This union helped propel Hellenic shipping into the global spotlight as American “royalty” tied up with the “Golden Greek” industrialist.

Onassis did not have the looks or power of Jackie’s first husband, the US president John Kennedy who was assassinated five years earlier in Dallas.
