President Jimmy Carter, who died Sunday at age 100, is leaving a lasting legacy after decades of work and one of the causes he cherished most, according to those who volunteered with him.
Since 1984, Carter and his wife, Rosalynn Carter, have been “a disruptive champion and voice for affordable and decent housing for all.” The habitat of humanity. The Carters donated their time and influence and worked with nearly 103,000 volunteers from 14 countries to build, renovate and repair 4,331 homes, the nonprofit said.

Rhode Island-based builder and designer Kenneth Young, 66, first began volunteering for Habitat for Humanity in the 1990s. After doing the “Carter build” in 1995 in Watts, California, a suburb south of Los Angeles, he “got the bug,” he told ABC News.
Since then, Young has done 20 builds, many with the 39th president of the United States, including Carter’s latest build in Nashville in 2019, Young said.
Young’s favorite story about Carter was during a construction site in Budapest, Hungary, in 1996, when residents of a newly built house — twin children — hit him in the face with a balloon and Carter, a grandfather himself, “took it. He steps up” and smiles.
“It was a classic,” Young said.

Don Shaw and Thomas Trumble — lifelong friends who have volunteered together for decades at the Hartford, Connecticut chapter of Habitat for Humanity — first worked with Carter in 2002 in Durban, South Africa, they told ABC News.
A major focus of the construction was apartheid reconciliation, and the project was part of Carter’s goal of building 1,000 homes in Africa, Shaw said.

Shaw and Trumble met with Carter in Mexico, India, Thailand, Canada and twice in Haiti, they said. They were also with Carter during his last build in Nashville.
Volunteers were often on first-name terms with Carter, who made them feel like part of his “inner circle,” Shaw said.
Although Carter’s celebrity and political status often brought a media circus and additional funding, the former president also knew how to get his hands dirty with volunteers.
On the job, Carter was a natural leader, Young said.

Carter’s presence alone was enough to motivate everyone to work hard and efficiently. The builds Carter led were “a logistical miracle,” Shaw said, and it was often surprising to see how many homes the team could build in a single week.
“President Carter, too the army man, and having that military background., he wants well. He wants to do it right. And he wants it on time,” Young said.

Shaw nicknamed Carter a “benevolent worker,” she said.
“President Carter was about getting the job done,” Shaw said. “I remember walking around the site saying, ‘No pictures, no pictures.’ We have houses to build. Come back.”
After an eight-hour day of work, volunteers would gather under a large tent and share a meal, Trumble said.
One of Carter’s favorite rituals was walking through completed houses to hand out keys and a Bible to new residents, Young said.
“He really cares about the people we’re building,” Young said.

Carter will be sorely missed, volunteers said.
“God knows we will all miss President Carter when he leaves us, but I hope his legacy will go on for a very long time,” Young said.
Shaw said: “Having the Carters around was magical.”
