Christina Nilsson, Countess de Casa Miranda, (20 August 1843 – 20 November 1921) was a Swedish operatic soprano. She possessed a brilliant bel canto technique and was considered a rival to the Victorian era's most famous diva, Adelina Patti. Nilsson became a member of the Royal Swedish Academy of Music in 1869.
Christina Nilsson was born Kristina Jonasdotter on Sjöabol farm, near Växjö, Småland, to the peasants Jonas Nilsson and Cajsa-Stina Månsdotter. From her earliest years, she demonstrated vocal talent. She taught herself to play on the violin and flute, and sang in the peasants' fairs in Sweden with her brother. She was discovered by a prominent civil servant when, aged 14, she was performing at a market in Ljungby. He soon became her patron, enabling her to have vocal training. She was a pupil of Franz Berwald for two years.
In 1860, she gave concerts in and Uppsala. After four years' study in Paris, she had her operatic début 1864 as Violetta in Giuseppe Verdi's opera La Traviata at the Théâtre Lyrique, Paris. After this success she sang at major opera houses in London, Saint Petersburg, Vienna and New York City. She also appeared in the Metropolitan Opera's inaugural performance on 22 October 1883 in Gounod's Faust. In September 1885 she was contemplating retiring from the spotlight, and held a farewell concert from the balcony of Grand Hotel in Stockholm. An estimated 50 000 people gathered to hear the world famous soprano. Suddenly a rumour spread that the scaffolding on a nearby building was falling down, and panic spread in the crowd. 19 people were killed in the chaos that followed, and the dead bodies and all the injured were brought to the hotel lobby, where a horrified Nilsson met them. The Stockholm police were criticized for the way they handled the event, and Nilsson never got over the accident. She donated generously to the families of the victims.
