Henrietta Rosch

Here's an article from a web site http://www.dcd.ca/exhibitions/vancouver/allkinds.html
quote: ..."While dance didn't yet have the stage to itself, appearing as it did as one part of an evening's entertainment, it was often deemed worthy of notice. When the Calhoun Opera Company mounted The Black Hussar at the Vancouver Opera House in 1894, for instance, the World reported on January 23: "The march of the ballet, attired as Black Hussars, was very well conducted and ... had to be repeated to satisfy the audience. The sabot dance was a novelty and was very well done; it had to be repeated as had also the skirt dance."

The next month, the Opera House presented M.B. Leavitt's spectacular production, Spider and Fly, with dancers from the Folies-Bergère. According to the World on February 17: "The ballet was well trained and embraced some shapely forms and some pleasant features.... The electric dance of Miss Henrietta Rosch was a novelty to Vancouverites, and a reappearance was demanded."
