"Tree of Knowledge, Tree of Light" was installed in 1991 at the Coolidge Corner Branch of the Brookline Public Library. This was the first piece of public art to be funded by the Brookline Arts Council. This site was chosen by the artist because of its exceptionally diverse population. The library is used by people of many cultures and economic backgrounds, by children and the elderly. The window screens an unfortunate view, while continuing to provide abundant natural light and a sense of the space beyond.
