Thekla Catharina Charlotta Hofer née Falck (1852–1938) was a Swedish operatic soprano and later voice teacher. She made her début at the Royal Swedish Opera in 1879 as Rosina in The Barber of Seville. In addition to performing in various theatres in Sweden, she was a highly applauded guest in Weimar, St Petersburg and Riga. In the mid-1990s, she retired from the stage to teach with pupils including Signe Rappe and Karin Branzell.[1][2][3]
