Yesterday marked Anne Frank’s 90th birthday. The United Nations unveiled a small tree that in the gardens of its headquarters to remember her legacy and the rest of victims that perished in the Holocaust.  The tree sapling is descended from the horse chestnut tree that grew outside the attic in which the Frank family hid for two years from the Nazis before the Nazis found them.

Anne Frank wrote in her diary about the chestnut tree on many occasions, such as an entry on Feb. 23, 1944.

“Nearly every morning I go to the attic to blow the stuffy air out of my lungs. From my favorite spot on the floor I look up at the blue sky and the bare chestnut tree, on whose branches little raindrops shine, appearing like silver, and at the seagulls and other birds as they glide on the wind,” she wrote.

Anne Frank was born on June 12, 1929. In 1942 the Frank family went into hiding in Amsterdam when the Germans occupied the Netherlands.  The family was arrested in August of 1944 and Anne Frank died less than a year later in the Bergen-Belsen concentration camp.

The Diary of Anne Frank was published by her father Otto who was the sole survivor from the family. The diary is a powerful memory of a time when hate ruled the world and a testament to the human spirit of a young girl.

UN Undersecretary-General Catherine Pollard spoke at the dedication by saying, “this sapling is a living symbol of both the legacy of Anne Frank and the values that the United Nations embodies.”

”The tree will stand as a beacon of hope, a living reminder of the importance of continuing the work for a just and peaceful world in which we celebrate diversity,” she said.
