Through saplings descended from the majestic horse chestnut tree that gave her so much pleasure in her bleak hideout, Anne Frank will soon have her story joined with that of the Little Rock Nine — the black students who integrated an Arkansas high school under the guard of 1,200 soldiers in 1957.

The school, Little Rock Central High School, is one of 11 sites dedicated to fighting intolerance that have been chosen by the Anne Frank Center USA in Lower Manhattan as the destination for saplings that originated from the tree in Amsterdam, now 150 years old. Anne often marveled as it changed through the seasons, blooming flamboyantly, then slowly losing its leaves, outside the small office building at 263 Prinsengracht where she and her family were hidden during the Nazi occupation. It was one of the few things she could glimpse for those two years.
