A diehard Communist, David Alfaro Siqueiros fought in the Mexican Revolution in the mid-1910s. Over the next several decades, he would revolutionize the theory and practice of muralism in Mexico and abroad, largely inspired by his radical politics. In 1940, his political convictions led to a less honorable enterprise when he spearheaded an assault on the home of Russian revolutionary Leon Trotsky as he and his family slept in their beds.    Show notes and full transcripts available at www.artofcrimepodcast.com.  If you'd like to support the show, please consider becoming a patron at www.patreon.com/artofcrimepodcast.
