Tulane's beloved Nutall Oak that served as the "Bead Tree" for over 30 years passed on and was replaced in 2020 with three 21-foot tall steel and acrylic "trees," known as the Bead Three. The trees were designed by architect and Tulane professor, Irene Keil, along with her husband, local artist, David Gregor, as a way to memorialize the Bead Tree.
