The Alexis de Tocqueville Institution (AdTI) was a Washington, D.C. based think tank. AdTI was named after the French historian Alexis de Tocqueville. Founded in 1988, its president was Ken Brown and its chairman was Gregory Fossedal. At its peak it had 14 full-time staff researchers. In 2006, the organization ceased most operations, issuing its last press release in 2007 to announce that its former chairman was running for President of the United States.
