Washington, DC -- The 76-foot-long mobile designed by Alexander Calder for the central court of the East Building of the National Gallery of Art has been removed from public view for the second time since its installation in 1977. National Gallery staff and engineers, including artist-engineer Paul Matisse (the grandson of Henri Matisse) disassembled the sculpture on April 19 in order to clean the multicolored parts and to repair the worn metal surfaces. The Gallery plans to reinstall it by the end of 2005. The unofficial icon of the East Building, Calder’s mobile consists of thirteen panels and twelve arms, weighs 920 pounds, and is constructed of aluminum honeycomb and aluminum and steel bars.

Calder (1898-1976) created his first motorized abstract sculptures or "mobiles" in the early 1930s. Using an ingenious system of weights and counterbalances, he eventually designed constructions that moved freely when suspended, powered only by slight air currents. The work he created for the East Building, Untitled(1976), is a prime example of this kind of construction.

In 1972, when the East Building of the National Gallery was under construction, the artist was asked to create a large mobile that would complement the monumental atrium of the building. Originally planned in steel, the sculpture was too heavy when enlarged to function as the artist intended. Paul Matisse transformed the design into an aluminum construction that retained the look and dynamism of the steel construction with a more employable weight. The sculpture was installed on November 18, 1977, one year after Calder died; it was his last major work of art.

In 1988, the mobile was removed from exhibition for conservation treatment for the first time. Since its refurbishment more than 25 years ago, the wearing of the metal parts has slowly impeded its free rotation. When it returns to its prominent perch in the East Building atrium, it will move about and look once again as Calder had envisioned it.
