Hundreds of people gathered Monday to celebrate the late Rosa Parks on what would have been her 100th birthday by unveiling a postage stamp in her honor steps from the Alabama bus on which she stared down segregation nearly 60 years ago. Parks, who died in 2005, became one of the enduring figures of the Civil Rights movement when she refused to cede her seat in the colored section of the Montgomery, Ala., bus to a white man after the whites-only section filled up. Her defiance and the ensuing black boycott of the city bus system helped Rev. Martin Luther King Jr. rise to national prominence.
