Working on the final part of the - incomplete - manuscript of memoirs, which did not come to the attention of researchers or of the public until 1926, when Hans Brix, professor of literature and HCA-researcher came across it at the Royal Library and published it under the name of Levnedsbogen (The Biography).
Publication of The Raven or The Test of Brotherhood. Magic Opera in Three Acts, (based on Gozzi's tragi-comic fairy-tale). Music composed by J.P.E. Hartmann. The title in Danish: Ravnen eller Broderprøven. Trylleopera i tre Acter, (efter Gozzis tragicomiske Eventyr). Musikken componeret af J.P.E. Hartmann.
In 1840, Robert Schumann commented on The Raven in Neue Zeitschrift für Musik:
"The writer has produced a magic opera, but not a stupid, childish one, such as those with which German composers so often have to make do. Rather it is a text marked by comprehension and meaning, and yes, even by poetry. One finds in it thoughts which are truly worthy of a poet, in fact of a remarkable life. The dialogue is also characterised by intellect and wit".
The poem "Lille Viggo, vil du ride Ranke?" (Little Viggo) - (written for Viggo Drewsen, born 1830) is printed in the magazine Nyeste Repertorium for Moerskabslæsning.
First performance at the Royal Theatre of Ravnen (The Raven) - "in honour of Her Majesty The Queen and Her Royal Highness The Crown Princess's esteemed birthday". The opera is performed a total of 10 times during HCA's life.
