Ten Things You May Not Know About President Jimmy Carter

As he releases his 28th book and heads to the Women in the World Summit, learn some surprising facts about the former president.

Former President Carter has been on the media circuit the last couple of weeks in support of his new book: “A Call to Action: Women, Religion, Violence and Power.” What you may not know is that he felt compelled to write it, his 28th book, after learning of what he refers to as “the worst human rights violation I had ever heard of”: that since the beginning of the 20th century, for political or religious reasons, more females have been murdered worldwide than all of the people who have died in every war during that same span of time.

Ahead of Carter’s interview with Katie Couric Friday, April 4th at 3PM EST at the fifth annual Women in the World Summit, here are ten more things you may not know about our 39th President:

1. Born October 1, 1924, he was the first US. President to be born in a hospital.

2. After literally stumbling over a homeless man sleeping in cardboard on a NYC sidewalk, Carter invited him to help on the first CarterWork Project for Habitat for Humanity in 1984. That man ended up living in and serving as the building’s superintendent for the rest of his life, more than 25 years.

3. Harry Truman is his favorite president.

4. During his inaugural address in 1977, Carter invoked the phrase “Human Rights,” establishing its modern usage and the concept we know today as those rights superseding any governmental law.

5. Upon leaving the White House, his aids and staff chipped in and bought him a Jeep as a going away present.

6. Unable for security reasons to make use of the Jeep (see #5), he traded it in for a state-of-the-art workshop outfitted with Craftsman tools.

7. Before addressing Congress on the signing of the Camp David Accords, Anwar Saddat warned him not to “aggravate the Israelis,” so at the last minute he added to his remarks Matthew 5:9:  “Blessed are the peacemakers: for they shall be called the children of God.”

8. He teaches bible study classes 35 Sundays a year at his local church and knows every verse of the bible.

9. As Governor of Georgia (1971–1975), he appointed more women and minorities to his staff, major state boards and agencies, and thejudiciary than all of his predecessors combined.

10. Carter gained his progressive civil and human rights views from his mother, Lillian, who at age 68 joined the Peace Corps and served in India.

Bonus fact: He wears a size 7 hat.
