Mentioned as violist in "The American history and encyclopedia of music" (numerous co-authors), 1908, page 382, article on Jaques Hoffmann. (Indeed, he was apparently the violist of the Hoffmann Quartet as of 1902 when the quartet was founded, apparently.) Er, ohoh. Are we talking about the Boston Symphony Karl Rissland (born in Germany, Konigssee spec., then to US) or his nephew (Karl Ernest Rissland, 1894–1971, born, died in USA) who also worked with Stokowski (in the San Francisco Symphony) - ouch! - info and bio of the latter here. Since Karl Rissland's arrangements (both here and his others) were chiefly made stringed instruments and his nephew was a wind player (trumpet mainly) this mean it is likely those of the elder Rissland we have here.
