Andy Warhol was an American artist known as the founder of POP art. As a child, he was often bedridden and found solace in drawing. His art featured repeated images of everyday objects and celebrities painted in bright colors. This included paintings of money, soup cans, and portraits of famous people like Marilyn Monroe and Muhammad Ali that he would recreate in different styles. Warhol's work was a major change from traditional art as it focused on popular and commercial images, and made him one of the most famous artists of the 20th century.
