In 1920, a young Australian seaman named Harry Bridges arrived in San Francisco, destined to become one of the most influential labor leaders of the 20th century. His life, legacy and profound impact on the American labor movement and its relationship with the rest of the world are explored in this two-part radio documentary. This broadcast is timed to coincide with celebrations at ports from San Diego to Seattle in honor of the anniversary of Bridges' 100th birthday this week. (Part 2 airs tomorrow night.)
