The Cleveland Orchestra has announced a $50 million gift from the Cleveland-based Jack, Joseph and Morton Mandel Foundation.

The largest gift in the orchestra's hundred-and-three-year history includes $31.5 million dedicated to endowment funds and the Jack, Joseph, and Morton Mandel Opera and Humanities Festival. The remainder will support and expand the orchestra's programs and partnerships, including boosting program and content choices through the orchestra's streaming platform, Adella. In recognition of the gift, the main performance space will be named the Jack, Joseph and Morton Mandel Concert Hall and the orchestra's building will be renamed from Severance Hall to Severance Music Center.

"The Mandel Foundation has made this grant because of the Mandel brothers' deep commitment to the vitality of Cleveland and a belief in the value of the humanities to shape an enriched spirit of life," said Jehuda Reinharz, the foundation’s president and CEO and its Stephen H. Hoffman chairman. "The world-class level of music of the Cleveland Orchestra is the embodiment of both, and with this gift we hope to help ensure that it will be available for generations to come."

"This unprecedented gift lays the groundwork for the Cleveland Orchestra's second century, supporting our long-term capacity to offer extraordinary musical performances and inspiring programs while transforming our ability to reach audiences far beyond the physical limits of our building," said Cleveland Orchestra president and CEO André Gremillet. "Like the orchestra, the Mandel Foundation combines a global outlook with a deep commitment to the Cleveland community. We will forever be grateful to the foundation for its extraordinary generosity."
