The Private Woman: Startling Claims from the New Biography

The most recent and significant update to the public's understanding of Jackie Kennedy comes from J. Randy Taraborrelli's biography, *Jackie: Public, Private, Secret*. The book, an instant bestseller, delves into the complexities of her inner life, revealing her as a strategic, deeply private, and sometimes ruthless protector of her family and memory.

1. The Ritualistic Burning of Letters and Photos

One of the most surprising claims is that in the years leading up to her death, Jackie engaged in a ritualistic process of burning personal letters and photographs. This act wasn't out of malice, but a deliberate, final effort to control her narrative and ensure that certain intimate details—especially those concerning her relationship with JFK and the aftermath of the assassination in Dallas, Texas—would never become public fodder.

2. The Complex Dynamic with Aristotle Onassis

While her marriage to the Greek shipping magnate, Aristotle Onassis, was often portrayed as a purely transactional alliance for security, the biography explores a more intimate and complicated private romance. Taraborrelli suggests their bond was rooted in a shared understanding of international fame and the need for a sanctuary away from the intense scrutiny of the Kennedy world.

The book highlights the competitive nature and deep, complicated love between the Bouvier sisters. Lee's death in 2019 brought renewed attention to their dynamic, with the new biography providing context on how their lives constantly intersected in the spheres of fashion, society, and romance.

Perhaps her most significant, yet often overlooked, achievement was her dedication to historic preservation. Her work began with the White House, which she transformed from a mere executive residence into a living museum, creating the White House Historical Association and securing artifacts.

6. Saving Grand Central Terminal

After leaving the White House, Jackie O became a fierce advocate for saving architectural landmarks in New York City. Her most famous victory was the fight to save Grand Central Terminal from demolition in the 1970s. She lent her celebrity, political savvy, and powerful voice to the Municipal Art Society's cause, writing a powerful public letter that galvanized public opinion and ultimately led to a landmark Supreme Court decision protecting the terminal.

7. The Later Years as an Editor

In her post-Onassis life, Jackie found a quiet, professional career as a book editor, first at Viking Press and later at Doubleday. This role allowed her to use her intellect and cultural authority, working with notable authors and further solidifying her reputation as a woman of substance beyond the First Lady title.
