The David and Francie Horvitz Family Foundation would pay the money over three years to match all other funds raised. That means other donors need to step up to double the value of their contributions.
The gift comes several months after NSU hired Bonnie Clearwater to lead the museum.
The Horvitz family is on the board of governors of the museum, and David Horvitz is the chairman.
“This inspiring challenge grant has already sparked an enthusiastic outpouring of support,” Clearwater said. “The museum has so far received nearly $300,000 in gifts as a response to this gift. David and Francie Horvitz have long recognized the importance of supporting the arts and community, and we are deeply grateful for their continued commitment to the museum. “
