In the Beginning
The closing months of 1944 marked a time of tense optimism in Springfield, as it was throughout the United States. The news reports from both fronts were generally good, and it appeared that the war in Europe might end within a matter of months. The devastating economic sacrifices of the war effort, and the depression years before it, were about to be supplanted by an era of postwar production and prosperity. It was against this backdrop that the Springfield City Council voted unanimously to purchase the assets of the privately owned Springfield Gas and Electric company, also the operator of the city transit system. The finalization of this transaction in 1945 marked the birth of City Utilities.
