Autograph Letter Signed, to another Theresa, with a reference to photography. In German. 2 pp. oblong 8vo, on her writing paper headed with mauve embossed initials, in good condition. 51 Finchley New Road, 24 July 1876. Thérèse Tietjens (1831-1877), leading opera and oratorio soprano. She made her career chiefly in London during the 1860s and 1870s, but her sequence of musical triumphs in the British capital was terminated by cancer. During her prime, her powerful yet agile voice was said to span seamlessly a range of three octaves. Many opera historians consider her to have been the finest dramatic soprano of the second half of the 19th century.
