President Obama on Thursday named the 16 recipients of the 2009 Presidential Medal of Freedom. America's highest civilian honor, the Medal of Freedom is awarded to individuals who make an especially meritorious contribution to the security or national interests of the United States, world peace, cultural or other significant public or private endeavors.

Described as "agents of change", the trailblazers include Billie Jean King and Sandra Day O'Connor, who broke through barriers for women, Sidney Poitier and Harvey Milk, who led the way for blacks and gays, and Stephen Hawking for the disabled.

President Obama said, "These outstanding men and women represent an incredible diversity of backgrounds.  Their tremendous accomplishments span fields from science to sports, from fine arts to foreign affairs.  Yet they share one overarching trait: Each has been an agent of change.  Each saw an imperfect world and set about improving it, often overcoming great obstacles along the way."
