Overshadowed by his famously funny brothers, Zeppo Marx was often remembered as the straight man of the legendary Marx Brothers. But behind his quiet screen persona was a talented businessman and inventor who dreamed of making things work rather than making audiences laugh. From Broadway and Hollywood to wartime engineering and innovative medical devices, Zeppo recalls his remarkable journey with humor, affection, and a few good-natured jabs at his family. Making His Marx is an entertaining biographical monologue about individuality, ingenuity, and discovering that success doesn't always come in the spotlight.
