Geller studied at the
School of the Museum of Fine Arts, Boston in 1921, and later taught there with
Karl Zerbe from 1943 to 1944. It was at the Museum School that she began painting with encaustic, a mixture of pigment and hot wax. She first received acclaim as a painter of "
organic abstractions" in the 1940s when she exhibited with a group of other emerging artists later known as the
Boston Expressionists. Her work was more abstract than that of Zerbe and other Boston
figurative expressionists. After marrying the composer
Harold Shapero in 1945, Geller continued painting and exhibiting, and taught art classes at the
DeCordova Museum in
Lincoln, Massachusetts. She was active as a painter for over seventy years. In 2012 her encaustics were shown in a major exhibit,
The Future of the Past: Encaustic Art in the 21st Century, at the
Mills Gallery in Boston. The exhibit also included a video demonstration by Karl Zerbe and an interview with Geller. Her works are included in the permanent collections of the
Boston Museum of Fine Arts, the
Addison Gallery of American Art, the
Danforth Museum, On October 22, 2015, Geller died at the age of 93. ==Influence==
