Lydia Mendoza: ‘Songstress of the Poor’
Published: 02 January 2008
Lydia Mendoza, singer and guitarist: born Houston, Texas 21 May 1916; married 1935 Juan Alvarado (died 1961; one daughter, and two daughters deceased); 1964 Fred Martínez; died San Antonio, Texas 20 December 2007.
Known as “La Alondra de la Frontera” (“The Lark of the Borderlands”), Lydia Mendoza was an iconic figure in Tejano music – which originated among Hispanics in Texas.
She was among the first female stars in an era when women played very much a subsidiary role in Hispanic-American culture, and her devotion to her working-class audience would see her dubbed “La Cancionera de los Pobres” (“The Songstress of the Poor”). During the course of a 60-year career she recorded hundreds of songs, many of them showcasing both her passionate vocals and the distinctive 12-string guitar style that she perfected to accompany them. …
In common with their fans, the Mendozas frequently encountered racism from the white majority. Lydia’s brother, Ramon Mendoza, later remembered their experiences in a particular west Texas town: “I hate to think back about how they treated people in places like that, but it’s part of our history. There was a restaurant in Levelland that had a sign right next to the door: ‘No Dogs or Mexicans Allowed.'”
