From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
Returns to Copenhagen.
The gas lighting is turned on for the first time in Copenhagen. The story "Gudfaders Billdedbog" (Godfather's Picture Book) is a series of depictions from the history of Copenhagen, from darkness to enlightened times - both literally and ideologically. The book describes the transition from the use of oil to gas for street-lighting as confirmation that a new age of enlightenment and humanity had begun.
