Subject is exactly Dietemann
Life Magazine outed a number of medical quacks in this expose, including Antone Dietemann, with a degree in sanitary engineering, was making on-the-spot diagnoses of illnesses "with a magic wand and an array of containers that hold various body tissues." A patient he diagnosed, Jackie Metcalfe, was actually an undercover agent for the state of California. Outside in a car, Life correspondent Joseph Bride made notes, hearing everything that transpired through a radio transmitter hidden in the agent's purse. Inside, Billy Ray, a photographer for the magazine, posed as the agent's husband to document the encounter. Life collaborated with officials in exchange for the right to publish the photographs.
