The Atlanta Symphony Orchestra has received a $1.85 million endowment gift from the Atlanta-based Mabel Dorn Reeder Foundation, The Atlanta Journal-Constitution has learned.

Calling it an “extraordinary gift,” ASO board Chairman Ben Johnson said the donation “adds to the future financial security” of the Southeast’s largest arts organization, whose endowment is worth roughly $70 million.

The ASO will establish the Mabel Dorn Reeder Honorary Chair in honor of the late Atlanta music lover, who died in 2007. A musician who demonstrates excellence in musical artistry, leadership, collegiality and community engagement will for five years occupy the chair, which comes with a one-time $10,000 stipend.
