The horse chestnut tree that Anne Frank wrote about in her diary while hiding from the Nazis has been battling fungus infestations, and at just under 200 years old it may get a new lease on life. CityRoom reports that the Anne Frank Center USA (run out of an office in SoHo) wants to plant ten saplings from the tree in U.S. cities, including New York. Executive director Yvonne Simons told the site, “What we really hope to do is plant them in areas across the U.S. as a symbol of the growth of tolerance,” and noted that the aim is to plant one around the National September 11 Memorial and Museum at the World Trade Center. In the '60s, Anne's father Otto said in a speech, "How could I have suspected... how important the chestnut tree was to her, as I recall that she never took an interest in nature. But she longed for it during that time when she felt like a caged bird."
