Diane Rehm is wrapping up a public radio career spanning more than four decades and thousands of episodes. Her talk show has originated at Washington, D.C.'s WAMU and is heard by nearly 3 million people across the country weekly on NPR stations.
Yet The Diane Rehm Show almost didn't get off the ground.
In 1979, Rehm started as a host with a program aimed at homemakers. Several years later, she informed her boss that she had other plans.
