On January 1, 1936, New York’s Lower East Side got its first subway stop, changing it from a land of crowded tenement dwellings and slums to a gentrified city district practically overnight. This is the story of the East Side Subway, איסט-סײַד אונטערבאַן. In Yiddish, the subway is called the unterban, though colloquially it was called the subvey which is how The Forward spelled it out for readers.
