Yma Sumac
Peruvian-American singer (1922–2008)

Zoila Emperatriz Chávarri Castillo (September 13, 1922 – November 1, 2008), known as Yma Sumac (from Quechua "Ima sumaq", meaning "how beautiful"), was a Peruvian-born vocalist, actress, model, musical composer and producer. She won a Guinness World Record for the Greatest Range of Musical Value in 1956. She has also been called "Queen of Exotica" and is considered a pioneer of world music. Her debut album, Voice of the Xtabay (1950), peaked at number one on the Billboard 200, selling a million copies in the United States, and its single, "Virgin of the Sun God (Taita Inty)", was a big seller in the United Kingdom, becoming an international success in the 1950s. Subsequent albums including Legend of the Sun Virgin (1952), Fuego del Ande (1959) and Mambo! (1955), were also successful.
In 1951, Sumac became the first Latin American and Peruvian female singer to debut on Broadway. In "Chuncho (The Forest Creatures)" (1953), she developed her own technical singing, named "double voice" or "triple coloratura". During the same period, she performed at Carnegie Hall and Lewisohn Stadium. In 1960, she became the first Latin American woman to get a phonograph record star on the Hollywood Walk of Fame.

Why this record matters
The phrase “peruvian-American singer (1922–2008)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q239030. VIAF identifies the subject as 306428720. The Library of Congress control number is no91012967. 4 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1922, 2008, 1956 and 1950.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
