She was one of the most  most admired and adored people of the twentieth century, and she captured our hearts.

And in commemoration of Jackie O’s would have birthday, here are 12 lesser-known facts about her fascinating life:

1. Starting at a young age, she was a talented equestrienne.

At just 3 years old, she was already able to control her pony. Imagine, she was already steering a massive animal despite just being a toddler just a year before.

2. The first time she visited the White House was as a tourist.

In 1941, a 12-year-old Jackie toured the White House with her mother and sister, but she found it extremely frustrating that there was so little information offered to visitors. So when she eventually moved into the White House herself, she made it her mission to fix this.

3. She was a brilliant writer.

In 1951, the 22-year-old submitted an essay to a Vogue writing contest, where the winner would earn a junior editor position for six months in New York and six months in Paris. And out of an impressive 1,279 entries, Jackie’s essay won the contest, but she quit on her first day.

4. In 1948, she was named “Debutante of the Year.”

Already stylish and graceful even as a teenager, Jackie was dubbed “Debutante of the Year” by Hearst columnist Igor Cassini.

5. Her first proposal did not come from JFK.

Before dating John F. Kennedy, Jackie was once engaged to a Wall Street banker named John Husted at the age of 22. She broke it off after three months in 1952, because she was reportedly hesitant about becoming a housewife.

6. Her wedding was the social event of the year.

Held in Rhode Island, there were 700 guests in attendance at the ceremony and a whopping 1,200 at the reception.

7. Her iconic pink suit was actually a reproduction of a Chanel design.

Chez Ninon, a New York fashion salon, actually created a line-for-line reproduction of Chanel’s design so Jackie could skirt around the ban on wearing foreign designers— a habit that she had been publicly criticized for in the past.

8. After JFK’s assassination, Jackie refused to change out of her bloodstained dress.

Though Lady Bird Johnson offered her a change of clothes at Lyndon B. Johnson’s swearing in, Jackie declined with a heartbreaking statement: “Oh no, I want them to see what they’ve done to Jack.” The outfit would go on to be one of the most famous artifacts from the day her husband was assassinated. It is now kept in a climate-controlled vault outside of Washington.

9. She had a knack for new languages.

Not only did she speak Spanish and French, she was also proficient in Italian and Polish. Here, she appeals to Latino voters with an ad entirely in Spanish.

10. Though she wasn’t a professional actress, she did win an Emmy.

Jackie’s televised White House tour exposed millions to the ins and outs of her restoration project on the iconic building, eventually earning her an Emmy.
