The Front Lines of Social Change. Veterans of the Abraham Lincoln Brigade. Talking with author Richard Bermack.

<p>The Abraham Lincoln Brigade was a group of about 3000 young, idealistic Americans who volunteered to fight in Spain against the fascists. When they returned in the late 1930s they maintained their social activism with support for the great causes of the 1950s, 60s and beyond. A memorial to their memory is under threat in San Francisco as a park is re-configured.</p>
