I see some articles that seem to refer to the same man as Chevalier Hubert Crispini or Chevalier Umberto Crispini. A Google search of Umberto Crispini brings up a PDF from a Music Trade Review of some sort, which won't come up for me. But when I click on an arrow to the right of it, it brings up a view of it. It includes a drawing of Mr. Crispini, and he has dark hair & a very similar mustache to your picture.
