Which painters are considered important figures in the impressionist movement?

Choosing the group that includes Cézanne, Degas, Monet, Manet, and Renoir highlights important figures in the Impressionist movement because they were foundational to this artistic style, which began in the late 19th century.

Each of these artists contributed significantly to the development of Impressionism. Claude Monet is often considered a central figure in this movement, with his practice of capturing light and atmosphere on canvas exemplified by works such as "Impression, Sunrise," which gave the movement its name. Edgar Degas is renowned for his unique viewpoints and depictions of movement, particularly in his ballet and café scenes. Pierre-Auguste Renoir is known for his vibrant use of color and light in his paintings of social gatherings and landscapes. Paul Cézanne, while later associated with Post-Impressionism, played a crucial role in evolving the principles of Impressionism and bridging the gap to modern art.

The other groups listed include artists known for various other styles that do not pertain to Impressionism. This distinction reinforces the significance of the artists in the second choice as pivotal contributors to the Impressionist art movement.
