Medal honour for Dylan and Glenn
President Barack Obama has presented the US Medal of Freedom to more than a dozen political and cultural greats at a ceremony in Washington.
The 13 recipients included Israel's president Shimon Peres, folk rocker Bob Dylan, astronaut John Glenn and novelist Toni Morrison.
In awarding America's highest civilian honour, the president took note of the overflow crowd in the East Room of the White House and said it was "a testament to how cool this group is - everybody wanted to check them out".
Mr Obama then spoke of his personal connection to a number of this year's recipients, calling them "my heroes individually".
"I know how they impacted my life," the president said. He recalled reading Morrison's Song Of Solomon in his youth and "not just trying to figure out how to write, but also how to be and how to think".
In college days, Mr Obama said, he listened to Dylan and recalled "my world opening up, because he captured something about this country that was so vital". Dylan's appearance drew the biggest cheers from the crowd, and he dressed for the event - sunglasses, bow tie and black suit embellished with shiny buckles and buttons.
Mr Obama also recalled reading about union pathbreaker Dolores Huerta when he was starting out as a community organiser. She co-founded the National Farmworkers Association, which later became the United Farm Workers of America. "Everybody on this stage has marked my life in profound ways," he said.
Mr Obama added that Pat Summitt, who led the University of Tennessee women's basketball team to more NCAA Final Four appearances than any other team, helped pave the way for his two daughters, "who are tall and gifted".
"They're standing up straight and diving after loose balls and feeling confident and strong," he said. "I understand that the impact that these people have had extends beyond me. It will continue for generations to come."
The Medal of Freedom is presented to people who have made meritorious contributions to the national interests of the United States, to world peace or to other significant endeavours.
