Carmen Herrera (Cuban, b. 1915) Carmen Herrera, who sold her first painting at the age of 89, was mostly unknown and unseen until 2009, when a large-scale survey of her work opened in the U.K. and she was deemed "the find of a decade" by the Observer. Herrera's geometric, hard-edged abstract paintings, influenced by her university degree in architecture and singularly focused on the interactions of space and color, prefigure the Op Art and Minimalism of artists like Ellsworth Kelly, Frank Stella, and Kenneth Noland.
