Before there was Captain America, there was The Mighty Atom. On this episode of Badass Jews, hosts Aaron Berg and Andrew Davidsburg dive into the unbelievable true story of Joseph Greenstein—a 5-foot-tall strongman with sidecurls, superhuman strength, and a heaping dose of chutzpah. He bent steel with his bare hands, bit through chains, and bashed bigots without breaking a sweat. From circus arenas to street fights with fascists, Greenstein wasn’t just strong, he was a one-man wrecking crew in a tank top.
