AUSTIN -- President Barack Obama is remembering Lyndon B. Johnson as a giant of a man whose efforts to pass the Civil Rights Act made real the promise of the nation's founders.
That is -- Obama says -- that all men are created equal.
The landmark law ended racial discrimination in public places.
Lyndon Johnson's presidency has long been viewed in the shadow of the Vietnam War, a conflict that saw American soldiers die in jungles half a world away while anti-war demonstrators chanted in the streets back home.
The summit will both look back at the civil rights movement and address issues still lingering in the U.S. and globally. Panel discussions will feature political and civil rights leaders and academics discussing topics from immigration and gay marriage to the role of sports in the civil rights movement.
Among those scheduled to participate are San Antonio Mayor Julian Castro, former congressman and United Nations ambassador Andrew Young and Bernice A. King, the youngest daughter of civil rights leader Martin Luther King Jr., and chief executive of The King Center in Atlanta.
The library also has a "Cornerstones of Civil Rights" exhibit that features the original Civil Rights Act of 1964 and Voting Rights Act of 1965, both signed by Johnson, and a copy of the 1863 Emancipation Proclamation signed by President Abraham Lincoln that declared all slaves in Confederate states free.
Updegrove said having Obama, the nation's first African-American president, visit the civil rights summit speaks to the success of Johnson's initiatives, particularly the Voting Rights Act, which protected the voting rights of millions of minorities across the country.
"You have in (Obama) one who likely would not have ascended to the nation's highest office if not for the civil rights legislation Lyndon Johnson put forth," Updegrove said.
Subsequent events in coming years will mark the 50th anniversaries of other Johnson initiatives, including Medicare, the Clean Air Act, seatbelt requirements and health warnings on cigarettes.
Vietnam was a "dark shadow that hung over the country and the Johnson legacy," Updegrove said. "We can quickly forget the successes of that era."
