Jackie Kennedy and Aristotle Onassis

In the late 1960s, the widow of President Kennedy had a secret romance with Aristotle Onassis, who was then the richest man in the world. Simon Watts spoke to Nico Mastorakis, a Greek journalist who visited Onassis’s yacht in disguise to confirm the relationship and secure a sensational scoop. Jackie Kennedy and Aristotle Onassis would go on to marry in October 1968 in a spectacular ceremony on the private island of Skorpios.
