From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
For the first time, it is permitted to build on some of the land outside Copenhagen's ramparts. Significant economic expansion after a period of stagnation in the first decades of the century caused a migration from country to town. This means that the number of inhabitants in Copenhagen at the time of HCA's death in 1875 was double that at the time of his birth in 1805 (approx. 200,000 compared to approx. 100,000).
26 January 1852
"Om Aartusinder" (Thousands of years from now) is printed in the newspaper 'Fædrelandet'.
HCA is painted by Frederik Ludvig Storch, who is originally from Kerteminde, but had worked in Munich for the past 21 years. Storch had just returned to Denmark.
