Under mounting pressure, Thomas P. Campbell has resigned as the director and chief executive of the Metropolitan Museum of Art, according to Robin Pogrebin of the New York Times. “I have decided to step down from my role as director and CEO of the Metropolitan Museum of Art in order to pursue the next phase of my career,” Campbell wrote in a letter sent to staff.

Pogrebin writes that Campbell’s departure comes after “months of growing complaints among staff members and some trustees about the institution’s financial health and his capacity to lead the largest museum in the country.” The Met’s president and chief operating officer, Daniel H. Weiss, will serve as interim chief executive after Campbell officially leaves in June.

Just last month, the museum delayed construction on its $600 million modern and contemporary art wing, citing a $10 million deficit, as artforum.com previously reported here. Not all was dire, however: The museum also reported record attendance last year.

Campbell spent fifteen years at the museum as a tapestry specialist before he was appointed director in 2009, succeeding Philippe de Montebello. Under Campbell’s direction, the museum invested $15 million in refurbishing the Met Breuer, formerly the Whitney Museum’s home, and secured a collection of Cubist artworks from Leonard A. Lauder valued at more than $1 billion.
