Yma Sumac
Opera Singer
Known as The Peruvian Songbird, Sumac was a soprano who had a five-octave range and released the single "Mambo!"
She got her break due to a close relationship with Moises Vianco, a bandleader.
Throughout the 1950s, she was a big supporter of exotica music.
She married Moises Vivanco on June 6, 1942; after their divorce in 1957, they remarried that same year.
She appeared on The Late Show with David Letterman in 1987.
