The Hyde Collection in Glens Falls, New York, has announced a gift of art and cash valued at $11 million.

The gift — the largest in the museum's history — from architect Werner Feibes includes more than a hundred pieces, or about two-thirds of the collection that Feibes and his partner, the late James Schmitt, accumulated beginning in the 1950s. The fifty-five works that make up the remainder of the collection were donated to the Hyde last August. The collection includes works by twentieth-century artists Josef Albers, Sol LeWitt, Grace Hartigan, Ellsworth Kelly, Robert Motherwell, Bridget Riley, and David Smith.

The cash portion of the gift, $1 million, will be used to build a new fifteen-hundred-square-foot gallery space, to be named the Feibes & Schmitt Gallery, dedicated to modern and contemporary art. The museum plans to launch a fundraising campaign to match a portion of Feibes' donation in support of the project.

A portion  of the Feibes/Schmitt's collection was displayed at the Hyde in 2001. In 2005, Schmitt joined the museum's Collections Committee, which approves acquisitions and exhibitions, and served on the committee until his death in 2013, two months after he and Feibes were married.

"This is a collection that would be welcomed by any major metropolitan museum in the country, and it's coming here," said Hyde director Erin Coe. "It's building a bridge....We're a museum known for Old Masters, historical art. This is building a bridge to the twentieth century and to the twenty-first century."
