At which New York museum did Georgia O'Keeffe have her first major retrospective in 1970?

Georgia O'Keeffe had her first major retrospective at the Whitney Museum of American Art in 1970.

The exhibition, Georgia O'Keeffe, was organized by the Whitney Museum of American Art in New York and opened in 1970. By then, O'Keeffe had already enjoyed decades of recognition for her flower paintings, New York skyscrapers, animal bones, and New Mexico landscapes. The retrospective presented the breadth of her career rather than treating her only as a painter of flowers.

The Whitney exhibition was a major late-career milestone. O'Keeffe was in her early eighties, and the show helped establish her importance across successive phases of American modernism. It is sometimes confused with later retrospective exhibitions, including the 1987 exhibition organized by the National Gallery of Art and shown at several museums. The 1970 event was specifically held at the Whitney.
