New York sidewalks and streets are a treasure of old manhole covers. Some are utilitarian, others decorative, but most are emblazoned with the name of the ironworks where they were made.
But this one, on the sidewalk on 11th Street east of Fifth Avenue, is more like a cast-iron advertisement for the M. J. Dempsey Foundry, located on West 55th Street.
Dempsey made furnace grates, coal hole covers, boiler castings, and dumping grates. It’s a small reminder of the great infrastructure advances (steam heat, coal delivery, furnaces) that helped make the city an manufacturing and industrial powerhouse.
