Minimalism refers to an art period between the 1950s-1970s that involved sculpture and paintings that focused on simplicity in both form and content. Individual expression was thrown out the window and instead artists focused on creating dramatic and intense experiences for their viewers as a result of the simplicity inherent in the objects. However, although Minimalism emerged around this time, it actually can be seen in effect in the 1700s when the, “Altar of Good Fortune” was created out of a cube and stone sphere by Goethe. In addition, other artists in the 1920s also created some artworks following the Minimalist theme. However, it was not until later the Minimalism came full-blown into the art world by artists such as Dan Flavin, Carl Andre, Ellsworth Kelly and Donald Judd. They were upset with Abstract Expressionism that included cold stark canvases, sculptures and installations. Minimalism has several cousin art movements, including Pop Art, Land Art and Conceptual Art. Conceptual Art tries to communicate a theory, Land Art focuses on simple shapes, and Pop Art tries to communicate the message of the impersonal. It was a popular art period and continues to impact artists today in the development of their ideas. Key artists of the movement include Frank Stella and Ellsworth Kelly.
