Henry Mortimer Rosenberg was an artist and printmaker.
Rosenberg studied at the Royal Academy in Munich, as well as in Florence and Venice. He was one of the 'Duveneck boys', followers of the American painter Frank Duveneck in Venice. The group also included Otto Bacher, John White Alexander, Robert Frederick Blum, Charles Abel Corwin, George Edward Hopkins, Harper Pennington, Julius Rolshoven and Theodore M. Wendel. In Venice they formed friendships with JW and Henry James.
The young painters were in awe of JW's experience and reputation. JW, who enjoyed their admiration, happily discussed his work and gave advice to the students. He used to come and sketch from the windows of the Casa Jankowitz on the Riva San Biagio in Castello where the group stayed. Rosenberg became quite friendly with JW, and in March 1881 JW and his mistress Maud Franklin asked to be remembered to Rosenberg who was at that point working in Florence with the Duveneck Boys [#11621].
In 1881 and 1882 Rosenberg exhibited his etchings, along with those of other Duveneck Boys, in London with the Society of Painter-Etchers and Engravers, a society which had formed in 1880 with JW's brother-in-law Francis Seymour Haden as a founder member. JW attempted to dissuade Otto Bacher from exhibiting: 'The Society of Painter-Etchers is already ridiculous and I intend that it shall die the death of the absurd. So just 'wait a bit' - and send nothing to this Seymour Haden game, for I give you the straight tip - it can't possibly succeed'. However, the exhibitions were very well received by critics.
Rosenberg was a member of the Salmagundi Club.
