RIP Rosalynn Carter

Rosalynn Smith was young Jimmy Carter's sister Ruth's best friend back in 1945 when he asked his sister to set them up. It was practically settled from the start that Jimmy and Rosalynn would work hard to make the world - beyond just Plains, Georgia - a better place.

Rosalynn Carter would go on to become one of the most politically active first wives in history, right up there with Eleanor Roosevelt. She has died at age 96 in Plains from dementia. 

While they served in the Oval Office from 1976 to 1980, they arguably went on to have much more influence in their post-presidential years. They focused largely on human rights and democracy and did a lot of Habitat for Humanity house building. She focused on mental health and, under her watch, the office of first lady became a federal position for the first time.

Jimmy is still alive at age 99 and their marriage is now the longest ever for a presidential couple at more than 77 years.
