Millard Fuller founded Habitat for Humanity International. He travels and speaks worldwide, and has received international recognition for his work in advocating decent, affordable housing for all in the US, Asia and other parts of the world.

A graduate of Auburn University in Alabama and the University of Alabama Law School, he and a college friend began a marketing firm while still in school. Fuller's business expertise and entrepreneurial drive made him a millionaire at age 29. Fuller and his wife, Linda, gave this all up to begin a poverty housing initiative that would eventually become Habitat For Humanity International. Their work grew out of a racial-reconciliation community located near Americus, in the southern US state of Georgia, and the model was refined in Zaire (now the Democratic Republic of Congo).

Fuller received the Medal of Freedom from former US President Clinton in September 1996, and was named the 1995 Builder of the Year by Professional Builder magazine. He and his wife were awarded the 1994 Harry S. Truman Public Service Award, and he also has received the Martin Luther King, Jr. Humanitarian Award. He continues to receive many honorary doctorates and achievement awards for his outstanding leadership and contributions toward meeting the goal of eliminating poverty housing worldwide.

In December 2003, Non-Profit Times of the US named him its "Executive of the Year".

Fuller participated in the World Economic Forum in Davos, Switzerland, in January 2004 where he spoke on a panel entitled “Setting the 2004 Agenda: Human Security”. He was a plenary speaker at the UN Conference on Shelter (“Habitat Two”) in 1996.  

Fuller is author of numerous books about the work of Habitat.

Fuller left the organisation in 2005.
