Today is Martin Luther King Jr. Day in the U.S. So I wanted to revisit an interview I did nearly 30 years ago with a woman whose actions helped propel Dr. King to national prominence.

In December 1955, a young woman named Rosa Parks was on her way home after a long hard day at work. She was on a bus in Montgomery, Alabama, when she was ordered to the back of the bus so a white man could have her seat.

She refused to move, and was arrested and jailed.
