During the Industrial Age, the city of Cleveland in Northeast Ohio was one of America's great trade and manufacturing centers.  A key link in a transport system of rivers, canals and railroads, Cleveland was home to steel companies and was the place where Standard Oil founder John D. Rockefeller made his fortune.  Its last "boom" years, however, came just after the Second World War, when its population peaked at 914,000 in 1949.  The second half of the 20th Century brought industrial decline, rising unemployment and racial unrest, culminating in 1978 when Cleveland became the first US city to default on its creditors since the Great Depression.   Dismissed in the press as "the mistake by the lake," Cleveland appeared to face the bleakest of futures.
