Casarella was hired by printmaker
Anthony Velonis, who during the 1930s had led the
Federal Arts Project in New York and expanded silk-screen printing as a fine art process. Velonis was commissioned to write a pamphlet on this technique,
Technical Problems of the Artist: Technique of the Silk Screen Process (1938), which was distributed to WPA art centers across the country. It was very influential in encouraging artists to try this process. The
New Deal program created employment opportunities for artists. In the 1940s, Velonis continued to lead Creative Printmakers Group in New York, which he had co-founded in 1939. Casarella printed
serigraphs at this studio. The following year Casarella created the poster for the 1943 exhibition,
Artists for Victory. Casarella joined the
U.S. Army in 1944 and fought in Europe during
World War II. After his discharge, he studied under the
GI Bill at the
Brooklyn Museum School from 1949 to 1951, including printmaking with
Gabor Peterdi. Casarella made his first paper relief print in about 1948. He continued to experiment with the medium throughout his career and developed a way of layering cardboard in order to cut it like a woodcut - an inexpensive way to produce large-scale works. His work was shown in 1949 at the Laurel Gallery in New York. In 1952 he was represented by
Margaret Lowengrund's Contemporaries Gallery. In 1953, Casarella and
Vincent Longo had their work shown in a joint exhibit at the
Brooklyn Museum. That same year Casarella's work was included in the
Young American Printmakers exhibition at the
New York Museum of Modern Art. In 1962, he was included in the widely traveled exhibition,
American Prints Today. Casarella received a
Fulbright Fellowship in 1951, a Tiffany Award in 1955, and a
Guggenheim Foundation Grant in 1960. These awards enabled him to travel for study and work throughout Italy and Greece. Casarella returned to the Brooklyn Museum to teach art classes from 1955 to 1960. During the 1960s, he shifted from printmaking to creating works of sculpture. He taught courses at the
Art Students' League and
Hunter College, with additional temporary teaching positions at the
Pratt Institute,
Yale University,
Rutgers University and
Columbia University. From 1969 to 1975, he taught at Cooper Union and
Finch College in New York City. ==Works==
