Otto returned home to Amsterdam alone.
There, he learned of the death of his wife and two daughters.
He had nothing to remember them by–he had lost everything.
But soon after his return, a friend gave him a very special gift.
It was Anne's diary.
The friend had saved the diary after the Frank family's arrest.
Otto kept the diary with him for many years.
He read it often, learning more and more about his young daughter.
He learned all about Anne's hopes and dreams.
Through reading the diary, Otto learned one specific dream.
Anne had wanted to write a book.
So, Otto decided to make Anne's dream come true.
He made Anne's diary into a book.
It is still very famous today!
Many people consider it one of the most important books of the 20th century.
From Anne's diary we learn about the Frank family history.
We learn what it was like to live as a Jew during World War II.
And we learn about the hopes of a young girl.
Over the years, Anne Frank's words and ideas have inspired many people.
For many people, her words represent the hope that people can live together in peace no matter what their religion, country or political beliefs.
As Anne writes, we are all different and yet we are all the same.
March 26, 1944: "Why should you be nicer to a rich woman than to a poor one?
Human greatness is not in wealth or power, but in character and goodness.
Give whatever there is to give!
You can always give something, even if it is a simple act of kindness.
People who give will never be poor!"
April 11, 1944: "I will make my voice heard.
I will go out into the world and work for mankind!
I know now that courage and happiness are needed first!"
July 6, 1944: "We are all alive, but we do not know why or what for.
We are all searching for happiness, we are all leading lives that are different and yet… the same."
