There is a famous black-and-white photograph from the era of the Third Reich. It is a picture taken in Hamburg, Germany, in 1936, of shipyard workers, a hundred or more, facing the same direction in the light of the sun.

His face is gentle but unyielding. Modern-day displays of the photograph will often add a helpful red circle around the man or an arrow pointing to him. He is surrounded by fellow citizens caught under the spell of the Nazis. He keeps his arms folded to his chest, as the stiff palms of the others hover just inches from him. He alone is refusing to salute. He is the one man standing against the tide. Looking back from our vantage point, he is the only person in the entire scene who is on the right side of history. Everyone around him is tragically, fatefully, categorically wrong. In that moment, only he could see it. His name is believed to have been August Landmesser. At the time, he could not have known the murderous path the hysteria around him would lead to. But he had already seen enough to reject it.
