Cody Cassidy is the co-author of the popular science book And Then You're Dead, which was translated into more than ten languages, and a former bookstore clerk in Buenos Aires.
While writing Who Ate the First Oyster? he attempted to shave with chipped obsidian like the inventor of the world's first razor, retraced the final steps of an ancient murder victim through the Pyrenees and the Alps, brewed beer by spoiling gruel, and fired a replica of an ancient bow and arrow, among other experiments. He lives in San Francisco.
