German soprano Frieda Hempel (1885-1955) was a highly intelligent woman whose repertory included some seventy operas. As to the rigors of being an opera singer, she once said: "It is a life of sacrifice from first to last. The public never believes this. They imagine us enjoying midnight suppers, bathing in champagne, and generally carousing. I assure you we are busy every minute and have time for nothing but work." She was the first Berlin and New York Marschallin in Der Rosenkavalier. She spent seven seasons (1912-1919) at the Metropolitan Opera. Seen here as the Goosegirl.
