Born in New York, Martha Diamond emerged as a significant figure in the city's art scene during the 1980s. Her practice was defined by a rigorous engagement with the urban environment, specifically the structural rhythms and verticality of the Manhattan skyline.

Diamond’s paintings are characterized by a unique synthesis of gestural abstraction and representational form. She often utilized bold, rhythmic brushwork to capture the essence of buildings and city streets, distilling complex architectural vistas into expressive, painterly compositions.

Following her death in 2023, her legacy has continued to gain international institutional recognition. The Martha Diamond Trust, in collaboration with David Kordansky Gallery and Thaddaeus Ropac, currently manages her estate, with a major European retrospective organized for the Sara Hildén Museum.
