U.S. civil-rights leader and former NAACP head Julian Bond, who also held elected office in Georgia for two decades, died at the age of 75 Saturday. Bond died in Fort Walton Beach, Florida, the Southern Poverty Law Center said in a statement. Bond was the civil-rights organization's first president. "Julian was a visionary and tireless champion for civil and human rights," SPLC said of its former president, who held the post from 1971 to 1979.

From 1998 to 2010, Bond was chairman of the National Association for the Advancement of Colored People.

The son of a university president and a librarian, Bond helped co-found the Student Nonviolent Coordinating Committee and was its communications director for five years in the early 1960s, canvassing the U.S. South to organize civil-rights and voter-registration drives and to lead anti-segregation protests.

In 1965, Bond was one of several African-Americans elected to the Georgia House of Representatives after the new Civil Rights Act and Voting Rights Act opened voter registration to blacks. Bond served four terms in Georgia's House and six terms in its Senate.

After losing a bid for the U.S. House of Representatives, Bond taught at several colleges and universities and became a published author. In later years, he was a regular commentator for "The Today Show," and even hosted NBC's late-night comedy show, "Saturday Night Live."

Bond was divorced and had five children, SPLC said. It did not give a cause of death.
