She began her artistic studied with muralist José Hernández Delgadillo in 1956, later marrying him and having three children, Beatriz, Francisco and Myriam.
She returned penniless to Mexico City, struggling to have a place to live and store her artwork.
[1][5][6][7] Her work has been compared to that of Frenchman Pierre Soulages, in that he was the only painter in Europe dedicated to the use of only black as she is the only one in the Americas to do the same.
[6] Eduardo Rubio wrote in 1988 that “the work of no other Mexican artist has unleashed so many passions and has been so misunderstood as … (hers).”[6] Painter José Zúñiga has stated that “Beatriz’s paintings are not understood, mostly due to the lack of information we have about present-day trends in art.
Earth is a fragment of that universe… Black is the full power of natural law and the base of my work.”[5] She also says “To put is simply, black is the theme because it is the absolute, it is cosmic and it implies the common and the sublime as part of life itself; it is also a means of communication as expression and as an end… it is the purpose of my work.”[1] Zamora had her first individual exhibition at the Antonio Souza Gallery in Mexico City in 1962.
[3][4] She has received three major grants for her work, two from the Consejo Nacional para la Cultura y las Artes (CONACULTA) in 1993 and 1997, and one from the Pollock-Krasner Foundation in New York in 2002.
