Which 1970 institution gave Georgia O'Keeffe her first major retrospective in New York?

The Whitney Museum of American Art gave Georgia O'Keeffe her first major New York retrospective in 1970.

The exhibition, Georgia O'Keeffe, opened at the Whitney Museum of American Art in 1970. It was a significant recognition of her long career and presented work from multiple periods, including flowers, cityscapes, landscapes, and bones.

O'Keeffe had exhibited widely before 1970, but a major retrospective offered a sustained survey rather than a selection of individual works. The exhibition helped confirm her importance to the history of American modernism and brought renewed attention to her achievement.

The Whitney is sometimes confused with the Museum of Modern Art, which also held important exhibitions of American art. The specific 1970 retrospective associated with O'Keeffe was organized by the Whitney.
