Less than two months after Richard Koshalek, the director of the Hirshhorn Museum and Sculpture Park in Washington, D.C. resigned, Constance Caplan, the chair of the museum’s board, has followed suit. Caplan announced her resignation in a strongly worded letter on July 8, 2013; she is the third member to leave the board since early June. Caplan cited lack of transparency, trust, vision and good faith as her reasons for leaving. Koshelek listed similar reasons in his resignation letter.

Staff members have been losing faith in the Hirshhorn since it embarked on its doomed Seasonal Inflatable Structure project in 2009. The project was continually stalled due to rising construction costs and conflicting feelings about the structure’s purpose. It was ultimately abandoned after Koshalek’s resignation.

The original vision was to create a 150-foot-tall bubble that would connect the inside and outside of the Hirshhorn and create additional space for installations and performances. Designed by Diller Scofidio & Renfro, the bubble was expected to cost over $12.5 million to create and install. Previous fund-raising efforts brought in about $7.8 million. When it was first announced, the Bubble garnered national attention and was applauded for being highly innovated.
