Thérèse Johanne Alexandra Tietjens (July 17, 1831 - October 3, 1877), soprano vocalist, was born in Hamburg, Germany.
Her voice was trained in Hamburg, where she made a successful debut in 1849 as Lucrezia Borgia in Donizetti's opera. She went on to to Frankfurt and Vienna. She sang for the first time in London in 1858, appearing as Valentine in Les Huguenots.
Her success was so great that for the rest of her life she made England her home, and soon gained as brilliant a reputation in concert and oratorio work as she had already won upon the stage.
She died in London on the 3rd of October 1877, having endeared herself to the English people as much by her private virtues as by her artistic gifts.
