A notice from the U. of Virginia Madison Hall Notes of November 13, 1915:
"With him comes the great Soprano Mme Loretta del Valle who for years was the leading prima donna in the opera house in Prague, Casse,l Mannheim other cities of musical note. Not only is Mme del Valle considered one of the finest sopranoes on the operatic and concert stage she has often been spoken of as one of the handsomest women now before the public ."

I can't find much on her. In her earlier career, she was known as Loretta Tannert.
