Georgia O'Keeffe was 98 years old when she died in Santa Fe, New Mexico, in 1986.
O'Keeffe was born on November 15, 1887, and died on March 6, 1986. Because her death occurred before her 99th birthday, her age was 98. She spent her final years in New Mexico, the state that had shaped much of her later work and public image.
Her long life covered major changes in American art. She trained in academic methods, encountered European modernism indirectly through Alfred Stieglitz's gallery, became a leading American modernist, and continued working into old age. Declining eyesight eventually prevented her from painting, but she remained involved in art and design projects.
O'Keeffe's age is sometimes misstated as 99 when people count the calendar years between 1887 and 1986 without checking the dates. The exact calculation depends on her November birthday and her March date of death.
