Which New York institution hosted Georgia O'Keeffe's major 1970 retrospective?

The Whitney Museum of American Art hosted Georgia O'Keeffe's major 1970 retrospective.

The exhibition was a landmark recognition of her long career and helped renew public attention to her work. By 1970, O'Keeffe had spent decades developing a personal vocabulary based on flowers, bones, buildings, landscapes, and abstract forms. The retrospective also contributed to renewed interest in her as a major American woman artist.

This exhibition should not be confused with her 1946 retrospective at the Museum of Modern Art, which was the first retrospective MoMA devoted to a woman artist. The Whitney Museum, founded in 1930, is especially associated with American art and maintains a major collection and exhibition program in New York City.
