It notes that while Degas participated in most Impressionist exhibitions, he denied being an Impressionist and preferred classical painting techniques. Mary Cassatt is introduced as the first American artist featured, known for her paintings of mothers and daughters. Cézanne is described as pioneering techniques that became the foundation for Cubism by treating nature as combinations of basic shapes.
