Carmen Barbosa was born on September 4, 1912, in the Catumbi neighborhood of Rio de Janeiro, as one of eight sisters in a modest family. From a young age, she exhibited a remarkable singing talent, although she was naturally reserved and preferred to avoid the limelight, even as her career began to flourish.
Barbosa's professional journey commenced in 1932, when her impressive vocal abilities led her to join the choir for Carmen Miranda's recordings with Victor. She made her radio debut on December 1, 1934, at Rádio Cruzeiro do Sul, later moving to Rádio Tupi. Her significant break came shortly thereafter, on December 23, 1934, when she stepped in for the ailing singer Madelou de Assis during a radio program. This transition from radio to record was a seamless progression for her.
She made her recording debut with Columbia, performing two sambas by renowned composers Pixinguinha and Cícero de Almeida. Throughout her career, she also recorded for Victor and Odeon, working with notable composers such as Herivelto Martins, Buci Moreira, Roberto Martins, Zé Pretinho, and Benedito Lacerda, who was both a close friend and a key supporter of hers. Lacerda often composed songs for her and played the flute on her recordings, contributing to her artistic output of 27 songs across 14 discs.
With her unique talent for samba and a beautiful voice, Carmen Barbosa established herself as a solo artist. She infused her recordings with her personality and the necessary nuance when the music called for it. Described as a striking black woman with black hair and dark brown eyes, she weighed 56 kilos and stood 1.58 meters tall. She was sometimes referred to as the Dark Star in various reports.
Barbosa continued her work at Rádio Club until her passing. During her time there, her colleagues included notable figures such as Sônia Barreto, Trio de Ouro, Francisco Alves, Gastão Formenti, Noel Rosa, and Antenogenes Silva. On December 30, 1939, due to illness, she was unable to attend an event organized by Rádio Clube, leading to Dircinha Batista performing her songs in her absence.
In 1940, despite suffering from diabetes, Barbosa continued to perform on the radio. That September, she took part in a season in São Paulo, appearing on Rádios Cosmo and Cruzeiro do Sul alongside Elisa Coelho and Orlando Silva. However, her performances became sporadic between 1940 and 1941.
By late 1941 and into early 1942, reports in the press expressed optimism regarding her return to the microphone at Rádio Clube. Unfortunately, her illness hindered her ability to work. Abandoned and in poor health, she was discovered at home by comedian Barbosa Junior, who rallied the artistic community to support her in her time of financial need. The Diário da Noite newspaper consistently reported on her struggles, providing both moral and some financial assistance from collaborators.
Despite her challenges, Carmen expressed a desire to return to singing: "Life is something else when you're healthy. And I'm dying to get back to the microphone. I want to sing a lot," she shared. She maintained a sense of optimism, asserting, "What's the use of crying? Smiling we forget. And forgetting is wonderful."
The Diário da Noite also voiced outrage at the neglect she faced as her condition worsened, noting that many who had once applauded her during her peak had disappeared from her life. However, some artists, including Moreira da Silva and Benedito Lacerda, organized a benefit show to support her.
In August 1942, Barbosa underwent an amputation of one leg, which further deteriorated her health. Although colleagues provided a mechanical leg, she was unable to use it before her passing. At the time of her death, she remained under contract with Rádio Clube, and its director, Renato Murce, defended the station against criticisms leveled by the press.
Carmen Barbosa passed away on September 3, 1942, at 8:16 PM, at her residence on Rua Bento Lisbôa. The death record indicated that she succumbed to cancer and tuberculosis. She was buried the following day, coinciding with what would have been her 30th birthday.
Even in her obscurity, Barbosa elicited sympathy from unexpected quarters. The Jornal do Brasil, although not fond of samba, acknowledged her plight in a note published on September 27, 1942, commenting on her death in poverty and the neglect she faced from many in the artistic community. Nonetheless, it highlighted that some artists dedicated to popular genres, including samba de morro, did step forward to assist her, countering the notion that all were indifferent to her struggles.
