Beginning in 1997, Havel hosted Forum 2000, an annual conference to "identify the key issues facing civilisation and to explore ways to prevent the escalation of conflicts that have religion, culture or ethnicity as their primary components". In 2005, the former president occupied the Kluge Chair for Modern Culture at the John W. Kluge Center of the United States Library of Congress, where he continued his research on human rights. In November and December 2006, Havel spent eight weeks as a visiting artist in residence at Columbia University. The stay was sponsored by the Columbia Arts Initiative and featured "performances, and panels centron his life and ideas", including a public "conversation" with former U.S. President Bill Clinton. Concurrently, the Untitled Theater Company No. 61 launched a Havel Festival, the first complete festival of his plays in various venues throughout New York City, including The Brick Theater and the Ohio Theatre, in celebration of his 70th birthday. Havel was a member of the World Future Society and addressed the Society's members on 4 July 1994. His speech was later printed in THE FUTURIST magazine (July 1995).
