Eidd, a Houston native, opened his gym in September of 1962. He had served in the Korean War as a physical therapist, helping rehabilitate wounded soldiers. “He told me his whole thing was to make people fit for the rest of their lives,” says Diamond. “He believed in the ability to change, to improve. That's what he cared about.” Eidd did not care about interior design: Nothing in the gym had been updated since he moved in. Those faded letters and magazine rip-outs on the wood-paneled wall behind him? The snippets of Scotch tape, older than some of his clients? The unbrushed hair? Those details make clear what wasn’t important to him, while that piercing gaze speaks to how he connected with people.
