When the Dunn Family, donated part of their land to Indiana University, they did so with one stipulation: that a specific tree, which had the initials of sweethearts from the Dunn family carved into the trunk, located on the property remain standing in the exact same spot where it had always been. When IU built the Chemistry Building they had to come up with a building plan that would not disturb the tree. So, they built around the tree and created a outside deck/courtyard area in the center of the Chemistry Building where the tree resides. In addition to the initials of the Dunn family, the tree now features initials and names of several generations of IU students. Courtney Deckard
