Jackie Kennedy, known for being the wife of former President John F. Kennedy, gained the nickname “Jackie O” during her second marriage to Aristotle Onassis, a Greek shipping tycoon introduced to her by her sister, Lee Radziwill.

It is said that Radziwill was romantically involved with Onassis while Jackie was still married to JFK.

Following the tragic assassination of President Kennedy in 1963, Jackie, concerned for her safety and that of their children, Caroline and John Jr., sought refuge in her marriage to Onassis for security.

Onassis, with his vast resources including an island in Greece, a private army, and an airline, provided Jackie with a sense of safety and abundance.

The union between Jackie and Onassis took place in 1968 on Skorpios, Onassis’ private island, with her children present.

Throughout their lavish and highly publicized marriage, Jackie evolved into the iconic figure of glamour known as Jackie O.

Despite being married, Jackie and Onassis spent minimal time together, primarily living on different continents.

Their arrangement seemed to suit them well, with Onassis emphasizing their freedom to do as they pleased without interference from one another.

Additionally, Onassis generously granted Jackie a $30,000 monthly allowance to maintain her luxurious lifestyle.

Kennedy cleverly managed her finances by utilizing the allowance to purchase high-end items, wearing them briefly before reselling them for profit.

This arrangement proved beneficial for both parties until tragedy struck in 1972 when Onassis’ son passed away, leading him to blame Jackie for the incident due to superstitions.

After the death of Onassis in 1975, where he left Kennedy a substantial inheritance, Jackie reflected on their time together, expressing gratitude for the beautiful experiences they shared.

Despite rumors of divorce looming, the couple remained married until Onassis’ passing, leaving Kennedy to later find companionship with American businessman Maurice Tempelsman until her own demise in 1994.
