Marvin Bentley Lipofsky was an American glass artist. He was one of the six students that Studio Glass founder Harvey Littleton instructed in a program at the University of Wisconsin-Madison in fall 1962 and spring 1963. He was a central figure in the dissemination of the American Studio Glass Movement, introducing it to California through his tenure as an instructor at the University of California, Berkeley and the California College of Arts and Crafts. Many of Lipofsky's works are colorful "bubbles" of glass. Often semi-translucent they allow the viewer to examine their depths. He is best known for the organic form of his pieces.
