Rebuilt family’s peanut warehouse
In his hometown of Plains, Georgia, Carter's parents, Earl and Lillian Carter, owned a peanut farm, warehouse and store. When Earl Carter died of cancer in 1953, Carter resigned from the Navy, came back home and worked to rebuild the business. Despite a drought in 1954 and a boycott against integration, Carter made the business profitable by 1959.

Devoted to humanitarianism
The Carter Center opened in 1982, and its mission, in partnership with Emory University in Atlanta, is to resolve conflicts and improve human health through a commitment to human rights. Part of that work led Carter to be honored with the Nobel Peace Prize in 2002.
Carter was diagnosed with stage 4 melanoma in August 2015. While teaching Sunday school at Maranatha Baptist Church in Plains, he said he had surgery on a mass on his liver and had radiation treatment on four melanoma spots in his brain.
Despite the diagnosis, Carter remained active in his humanitarian work, helping build a Habitat for Humanity house in Memphis, Tennessee.

By December 2015, Carter said, "My most recent MRI brain scan did not reveal any signs of the original cancer spots nor any new ones."
In May 2016, Carter Center director of communications Deanna Congileo confirmed that Carter did not need any more treatments but would "continue scans and resume treatment if necessary."
