Cleveland was the original Metropolis. Literally. When Clevelanders Jerry Siegel (who came up with the idea for Superman) and Joe Shuster (who drew him) introduced Superman, the world's first superhero walked the streets of their hometown, not the more auspicious-sounding fictitious city he lived in later.
More than 70 years have passed since Jerry Siegel hatched the idea for Superman in this house on Kimberley Avenue, and his creation has long had a life of its own, one far removed from its humble beginnings in a Jewish neighborhood of Cleveland. No one casually driving through Glenville would ever associate it with the Man Of Steel, but long before 10622 Kimberley Ave. was an actual, city-recognized landmark, it was a place Superman fans would visit to pay homage.
