In The San Francisco Nexus in World War II: Freedoms Found, Liberties Lost, and the Atomic Bomb, Meza tells the story of important events in the San Francisco Bay Area that have consequences still felt to date. He traces the invention of the atomic bomb, from a speculative design for a nuclear weapon sketched on a chalkboard at Berkeley by theoretical physicist Robert Oppenheimer and helped made real by "Big Science" that was pioneered by his friend and colleague, experimental physicist Ernest Lawrence. During this time, Black Americans migrated to San Francisco to escape the Jim Crow South, finding new freedoms, good jobs, and a leader in a singer-turned-welder named Joseph James. Meza shows how James fought for and won an end to segregation in his union, taking a large step toward the civil rights movement. At the same time, Japanese Americans were forced from their homes by a tragically misguided presidential executive order, upheld by the US Supreme Court, illustrating the fragility of liberty in America. These events continue to shape the world today.
