I remember going with my father in March 1848 on Sunday evenings to the musical receptions of Madame Dulcken, pianist to Queen Victoria, in Harley Street. She was the sister of Ferdinand David, professor of the violin at the Leipzig Conservatoire the intimate friend of Mendelssohn, who dedicated his Violin Concerto to him. I find in my diary: "Sunday, March 10th. After tea went to Madame Dulcken, where I accompanied Steglich (the famous horn player) on the piano. Molique and Berlioz were there. She lives in a fine house; there is a good piano in every room."
