Jackie Kennedy, LIFE Commemorates Anniversary Of First Lady's Birthday With Unpublished Pictures

Had she been alive today, Jackie Kennedy would be well into her twilight years, but would doubtlessly still be touted as one of the world's leading style figures.

Commemorating what would have been her 83th birthday (on July 28), LIFE.com has revealed a selection of pictures never published by the magazine.

Featuring Jackie as she accompanied her husband, future President John F Kennedy on the campaign trail and during the election, the black and white shots cement the New York debutante's eventual reputation as one of the most iconic women of all time.

LIFE.com writes: “Looking back now, even in the light of all we know about her fraught, strained, ‘storybook’ marriage to an obsessively philandering husband, there does seem to be something special about Jackie Kennedy.

“Maybe it’s just that the camera loved her. Maybe she was so intriguing to so many people simply because, set beside the other prominent women in Washington, DC, in the early 60s, she was young, chic and, with her Irish and French ancestry, indefinably and refreshingly “exotic”.

Jackie, who married Aristotle Onassis after the assassination of her husband, died at the age of 64, following complications from cancer.

Earlier this month the John F Kennedy Hyannis Museum opened a special summer exhibit on Jackie’s life.

The exhibit includes photos, handwritten letters and other mementoes from her time on Cape Cod.
