It's the evening of February 20, 1939, at Madison Square Garden in New York City.

26-year-old plumber Isidore Greenbaum silently rages at the people cheering all around him. Holding his

hands at his side, Isidore clenches and unclenches his fists and tries not to let his anger

show. Up on the stage in front of him is a 30-foot painting of George Washington. The first

president of the United States is flanked by the stars and stripes and two giant swastikas.

Isidore is in the middle of a crowd of supporters from the German-America Bund.

The Bund advertises itself as a place where Germans in America can reconnect with their homeland.

But its leader, Fritz Coon, is an ardent supporter of the Nazi party, and he has

attracted a crowd of 22,000 fellow believers to this rally in the heart of New York. Many wear

Nazi arm bands and uniform stormtroopers stalk the aisles. But not everyone here is a fascist.

Young Plummer Isidore is a Jewish emeritus who snuck into the rally to

witness it firsthand. He's already listened to hours of hate from the speakers on stage, but now

he watches with disgust as Fritz Coon himself struts out to a hero's welcome. Coon begins his

diatribe, and with each mocking and hate-filled statement, Isidore becomes more and more angry.

Kuhn's audience, though, responds with laughter, cheers, and Nazi salutes.

It's too much to bear.

So Isidore pushes his way through the crowd and charges onto stage right at Fritz Kuhn himself.

Kuhn startled, angry, and afraid, but Isidore doesn't

attack him. Instead, he grabs the microphone cable and yanks it hard, silencing the fascist

tirade. And as the crowd booze him, Isidore manages to scream down with Hitler before the stormtroopers

of the Booms tackle him to the ground.

Isidore Greenbaum is not the only New Yorker to stand up to Nazis that night.
