American Impressionism is an art movement that emerged in the late 19th century, influenced by the original Impressionism from France. American artists began to adopt similar techniques, focusing on capturing light and color in their work. They often painted outdoor scenes, emphasizing the effects of natural light on landscapes and everyday life. Key figures in American Impressionism include artists like Childe Hassam and Mary Cassatt, who explored themes of modern life and the American experience. This movement marked a shift towards a more personal and expressive style, paving the way for future developments in American art.
