Jimmy and Rosalynn Carter left behind enduring nonprofits as part of their legacy of giving back

President Jimmy Carter 's legacy of giving back endures in several nonprofits he and his wife, Rosalynn Carter, supported for the almost 50 years after they left the White House. In Los Angeles on Monday, members of Habitat for Humanity of Greater Los Angeles signed wooden two-by-fours that will be used in a new house as a tribute to the former president, who died at age 100 on Dec. 29. In Houston, they are planning to let members of the community sign a door and wall in a new house to remember the thousands of homes the Carters helped build.
