The man who did most to bring opera to Scotland (and indeed Britain) in the golden age of opera, the late nineteenth century, was Karl Rose, a native of Hamburg and by turns a citizen of the USA and finally of Britain. He was active in Britain with Carl Rosa Opera from 1873 until his death in 1889, at the early age of 47. Histories, memoirs and biographies proved of little use in uncovering details of Rosa’s business model, and of his opera tours. Current research would not have been practicable before the digitisation of newspapers accelerated the search process. They represent a critical resource, not least as newspapers in those days carried more detail in both advertisements and reviews than they do today. Iain explains his research in this podcast.
