From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
1857Meets Clara Heinke
First mention in the diary of Anna Bjerring, a 25-year old teacher from Ålborg, a town in the north of Denmark. On this day, HCA notes that he has received a letter from "Anna in Aalborg". This wording implies that they were already acquainted or had an even greater degree of familiarity, which indeed seems likely in light of her writing to him during his stay in England. (The first mention of her in the almanac is from 1858, a birthday greeting to him from "Anna in Aalborg"). From this time on, a life-long correspondence develops and they meet in person on several occasions. There is no doubt that she had strong feelings for HCA and did what she could to get him. At her death (1902) she took the letters from him with her in the grave!
Drives to Maidstone, where he takes leave of Dickens. By ship to France from Folkestone. Via Boulogne and Amiens to Paris. Is in Paris from 17th - 21st. The stay here is embittered by his reading negative reviews of the novel. Continues via Strasbourg, where in the cathedral he sees:
"a unity, like that which is present in every work of nature. One would think it had been created by nature itself", (the diary, 22nd July).
Then on through Mannheim, Frankfurt and Guntershausen to Leipzig (arriving 25th). Visits the publishers Lorck and Wiedemann and continues on the next day to Dresden, where he is met by the Serres.
Goes with the Serres from Dresden to see the estate of the pianist and composer Adolf Henselt in Schlesien. Mrs Henselt has a portrait of HCA hanging in the bedroom. During the stay here, Pastor Robert Matthäi draws (29th July) HCA reading "The Little Mermaid" at Gersdorf.
Back to Dresden with the Serrres. Is mainly at Maxen until 31st August, but in between he also stays in Dresden with the Serres..
First meeting with the painter Clara Heinke, who HCA had corresponded with during the past 4 years. In a letter she suggests a meeting in Dresden (during which her aunt acts as chaperone). HCA feels that she looks somewhat Jewish. Spends some time with her during the next few days and notes on 13th:
"All the ladies teased me [...] for having been so charming towards the young lady today. Clara Heinke seems to be an intelligent girl. She was very cordial towards me".
1st - 6th September
In Weimar, where he joins the grand duke in celebrating the unveiling of the statues of Goethe and Schiller (feels he and Schiller look alike). Meets Liszt and attends a concert with orchestral music by Liszt;
"...it was wild, melodious and unclear. Sometimes symbols were sounded. When I first heard it I thought a plate had been dropped. I went home weary; it was that damned music", (the diary, 5th).
6 September 1857
Travels home via Kassel, Hannover and Hamburg. Takes the steamship Eideren from Kiel to Korsør. Goes straight to Copenhagen, rather than stopping at Sorø, due to illness.
Due to another outbreak of cholera in the city, HCA leaves Copenhagen again. Goes to Roskilde, where he stays with Dean Ortved. Continues to the Ingemanns in Sorø on 17th. Receives a visit here from the poet Fr. Paludan-Müller and his wife. Paludan-Müller is an old school-friend of HCA. Continues on 26th to Slagelse, where he is met by Mrs Scavenius and her children and taken to Basnæs Estate. Is sick most of the time spent here. Has a heated discussion about religion with Mrs Scavenius.
