Georgia O'Keeffe made significant contributions to modern art, particularly through her pioneering style that emphasized large-scale floral paintings and landscapes of the American Southwest. Often considered the "Mother of American modernism," O'Keeffe's work bridged the gap between abstraction and realism, capturing the essence of her subjects with vibrant color and form. Her unique perspective on nature, along with her exploration of feminine identity in art, challenged traditional norms and expanded the boundaries of artistic expression. O'Keeffe's legacy continues to influence contemporary artists and is celebrated in museums worldwide.
