Notorious celebrity: David Duke

The modern-day voice of white separatism and racial segregation is David Duke, a former Grand Wizard of the Ku Klux Klan.

In his college days at Louisiana State University, Duke celebrated Hitler's birthday and often wore a Nazi uniform on campus--a harbinger of things to come.

In 1967, Duke joined the Klan, an organization he later tried to update. Goodbye pointey-headed white robes, hello coats and ties. In 1978, Duke and the Klan parted ways, and he formed his own organization,the National Association for the Advancement of White People.

During a long career, Duke has represented Louisiana as a state representative and has run unsuccessfully for the Louisiana Senate, both the U.S. Senate and House, Governor of Louisiana, and President of the United States. He has kept in front of his public with an Internet radio show of his own.

In 2002, he pled gulity to tax evasion and was given a term of 15 months in prison. He was released in 2004. He has authored books, including his own version of Hitler's "Mein Kampf," titled "My Awakening."

As of 2009, he was living in Austria.
