The term "American Impressionist" refers to a group of artists in the late 19th and early 20th centuries who were influenced by the Impressionist movement that began in France. These artists focused on capturing light, color, and everyday scenes, often painting outdoors to depict the changing effects of natural light. Notable American Impressionists include Childe Hassam and Mary Cassatt. American Impressionism is characterized by loose brushwork and vibrant colors, emphasizing the momentary effects of light. This style was a departure from the more formal and detailed techniques of earlier American art, allowing artists to express their personal impressions of landscapes, urban life, and social gatherings.
