Marietta Piccolomini was an Italian soprano. She was most famous for the role of Violetta in La Traviata by Giuseppe Verdi, which she performed in England, France, and the United States, as well as her native Italy. After her marriage in 1863, she retired from performing, making only rare charity or courtesy appearances thereafter.

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.
