Catalyst was commissioned for Minnetrista by Virginia B. Ball to honor her husband, Edmund F. Ball. The design represents partnership, giving and stewardship which were important ideals of Mr. Ball. It was also intended to represent a century of giving by the Ball family, their stewardship of the land, and Minnetrista as a catalyst in the community. The sculpture was dedicated in June 2004. The artist is Beverly Stucker Precious of Indianapolis.
The completed sculpture is comprised of 32,000 pounds of limestone, 17,000 pounds of stainless steel and 2,000 pounds of dichroic and plate glass. Forty-four hundred hours went into the fabrication of steel for Catalyst, which is 26 feet in diameter. It is located at the main entrance to Minnetrista.
