From the college’s news release:
Clifford Ross, chairman of the Helen Frankenthaler Foundation board of trustees and a nephew of the artist, said, “Helen‘s education at Bennington was critical to shaping her sensibility as a young artist, nurturing a spirit of risk-taking, experimentation, and inquiry that formed the basis of her creative process. The foundation is delighted to be making this gift.”
Frankenthaler had three solo shows at Bennington, and served as a trustee between 1967 and 1982.
It sounds like she had a pretty good time in college. Here’s a tribute she gave to the school in 2007, from the news release: “All of my Bennington memories melt into one joyful stream of laughter, invention, serious concerned pursuits, intense friendships, and the opening of my already ‘analytic mind.”
