In 1965, Hart’s sister, Chesley, was diagnosed with
leukemia. Because her parents were unable to cope with the illness, Chesley's Aunt Grace became her
caregiver. Hart tried to stem his family’s disintegration by helping Aunt Grace as much as he could. As he said: Art must ”give hope to the darkness.” It ”must be a part of life. It must be an enriching, ennobling and vital partner... It should be a majestic presence in everyday life." While working at Giorgio Gianetti Studio of Architectural Sculpture, he assisted sculptors
Felix de Weldon, Carl Mose, Don Turano, and Heinz Warnecke. He was on his way to becoming a master carver himself when the Cathedral Building Committee announced a major competition.
Creation Sculptures In 1971, the
Washington National Cathedral Building Committee held a competition to determine the appearance of the west façade, the main entrance of the Cathedral. This was not just an important commission, it was a radical break with tradition. In the past, the west façade of a Christian cathedral typically featured a depiction of the
Last Judgment; however, the Cathedral Building Committee wanted Washington National Cathedral to be the exception. Instead of the traditional image of judgment and destruction, they wanted to emphasize a message of love and affirmation, and so they specifically asked artists to focus on the theme of
Creation. In developing
Ex Nihilo—the central sculpture, by far the largest of the group—Hart studied the combination of figurative and abstract forms in
Rodin’s massive sculpture,
The Gates of Hell. As a complete sculptural ensemble, the
Creation Sculptures constitute "the most monumental commission for religious sculpture in the United States in the twentieth century." Just as in the competition for the Cathedral Building Committee, Hart's initial plan was not accepted. His team placed third. Hart conceived a sculpture of three soldiers "not at the apex [of the wall], as originally planned[,] but 400 feet away from the wall as if looking for their own names." Hart had become a master carver in 1974, and instead of continuing to work exclusively as a carver, he hoped to build on the success he had already won with more commissions sculpting national monuments. Carter said he liked the portrayal: "It was that image that put me in the White House and the governor's office, and I hope I can remain . . . (like that) in the future," he said.
Works in acrylic In 1972, Hart opened his own sculpture studio, to create original artwork, and execute commissioned pieces. As seen in
Elegy (1990), Hart developed an original process for embedding one acrylic sculpture in another. In honor of the Pope's fifty years of priesthood, Hart presented an acrylic work titled
The Cross of the Millennium to
Pope John Paul II in a ceremony at the Vatican in 1997. When it was unveiled, Pope John Paul II called the sculpture “a profound theological statement for our day.” Today, much of what he sculpted in acrylic remains in private collections. Among these pieces, Hart's later works tend to be "distinguished by an allusive rather than representational nature." ==Later life==
