The Massachusetts College of Art and Design's latest fund-raising campaign got a big boost from alumnus Arne Glimcher, one of the world's leading art dealers. Glimcher, the founder of Pace Gallery, gave a $1 million gift to MassArt's Unbound: Campaign for the Bakalar & Paine Galleries, which is seeking to raise $12 million to revitalize the three-floor gallery space on Huntington Avenue. So far, the school has raised $7 million of the total. The renovation of the Bakalar & Paine Galleries is the final phase of the college's $140 million campaign, launched in 2010, to transform the MassArt campus. "We are incredibly fortunate to announce this campaign with one of the largest gifts in the history of the college by one of MassArt's most esteemed alumni," MassArt president David Nelson said of Glimcher's gift. In addition to being a renowned art dealer, Glimcher is a movie producer and director. In 1992, he directed "The Mambo Kings," based on Oscar Hijuelos's book "The Mambo Kings Play Songs of Love." Glimcher was nominated for a best original song Oscar for the film's "Beautiful Maria of My Soul."
