From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
HCA sends a petition containing a poem to N.F.S. Grundtvig. At approx. this time he also contacts B.S. Ingemann, hoping to gain support for his attempt to move up in the world. Just Mathias Thiele, the publisher of Danske Folkesagn (Danish Legends) (released 1819-23), is another of the persons HCA gets to know during this year.
