In the 1930s, Victor Hugo Green worked as a postal carrier in Harlem but his girl lived in Richmond, Virginia, so he faced many challenges along the eastern seaboard “traveling while black.” Black motorists often ran into unspoken discrimination, making it more difficult to know if they would be welcomed or threatened with vandalism, assault or even death. With the input of other postal workers, Green created The Negro Motorist Green Book to help drivers safely navigate the roads during the Jim Crow era, 1936-67.
