At which museum was Georgia O'Keeffe's 1970 retrospective held?

Georgia O'Keeffe's 1970 retrospective was held at the Whitney Museum of American Art in New York City.

The exhibition was a major institutional recognition of O'Keeffe's career and helped reinforce her status as a central figure in American modernism. By then, her work had already passed through several major phases, including abstraction, New York cityscapes, enlarged flowers, and New Mexico subjects.

The Whitney Museum was founded to focus on American art, making it an especially relevant venue for a survey of O'Keeffe's achievement. The retrospective also arrived when renewed attention was being paid to women artists and to the history of modern art in the United States.

This exhibition is distinct from her first major retrospective at the Art Institute of Chicago in 1946. Both museums played important roles, but the 1970 event belongs to the Whitney.
