Early life

Úrsula Hilaria Celia de la Caridad Cruz Alfonso was born on 21 October 1925, at 47 Serrano Street in the Santos Suárez neighborhood of Havana, Cuba. Her father, Simón Cruz, was a railway stoker, and her mother, Catalina Alfonso Ramos, a housewife of Haitian descent who took care of an extended family. Celia was one of the eldest among fourteen children living in the house, including cousins and her three siblings, Dolores, Gladys, and Bárbaro, and she used to sing cradle songs to put them to sleep. According to her mother, she began singing as a child at 9 or 10 months of age, often in the middle of the night. She also sang in school during the Fridays' actos cívicos and in her neighborhood ensemble, Botón de oro.

While growing up in Cuba's diverse 1930s musical climate, Cruz listened to many musicians who influenced her adult career, including Fernando Collazo, Abelardo Barroso, Pablo Quevedo, Antonio Arcaño and Arsenio Rodríguez. Despite her father's opposition and the fact that she was Catholic, as a child Cruz learned Santería songs from her neighbor who practiced Santería. Cruz also studied the words to Yoruba songs with colleague Merceditas Valdés (an akpwon, a Santería singer) from Cuba and later made various recordings of this religious genre, even singing backup for other akpwons like Candita Batista.

As a teenager, her aunt took her and her cousin to cabarets to sing, but her father encouraged her to attend school in the hope she would become a teacher. After high school, she attended the Normal School for Teachers in Havana with the intent of becoming a literature teacher. At the time being a singer was not viewed as an entirely respectable career. However, one of her teachers told her that, as an entertainer, she could earn in one day what most Cuban teachers earned in a month. From 1947, Cruz studied music theory, voice, and piano at Havana's National Conservatory of Music.

One day, her cousin took her to Havana's radio station Radio García-Serra, where she became a contestant in the "Hora del té" amateur radio program. It was her first time using a microphone and she sang the tango "Nostalgia" (as a tribute to Paulina Álvarez), winning a cake as the first prize for her performance. On other occasions she won silver chains, as well as opportunities to participate in more contests. She also sang in other amateur radio programs such as La suprema corte del arte, broadcast by CMQ, always winning first prize. The only exception was when she competed against Vilma Valle, having to split their earnings: 25 dollars each.

In 2004, the Miami Herald revealed from partially declassified US State Department papers that Cruz had been linked to Cuba's pre-Revolution communist party, the Popular Socialist Party (PSP), as early as the 1940s. The article, promoted as an "exclusive", was written by Miami Herald journalist Carol Rosenberg from Freedom of Information Act requests. It made several revelations. Among them, the US Embassy in Havana denied Cruz a US visa in 1952 and 1955 because of suspected communist affiliations. The article also states that Cruz had joined the youth wing of the PSP at age 20 and had used a concert to arrange a secret meeting with communists in South America on behalf of its then general secretary, Blas Roca Calderío, who has also founded the party in 1925. Cruz had also signed a public letter in support of one of the Party's front groups, the Pro-Peace Congress. The article states that Cruz's surviving husband, Pedro Knight, was asked about this, and is quoted he knew nothing about it. "She never told me about that. She never talked about politics," the article quotes Knight.
