Antonio Giuglini was an Italian operatic tenor. During the last eight years of his life, before he developed signs of mental instability, he earned renown as one of the leading stars of the operatic scene in London. He created several major roles for British audiences, appearing in the first London performances of Gounod's Faust and Verdi's Un ballo in maschera. In London, he was the usual stage partner of the great dramatic soprano Thérèse Tietjens.

Thérèse Carolina Johanne Alexandra Tietjens was a 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.
