"Anyone who reads the passages that have now been discovered will be unable to supress a smile", Frank van Vree, director of the Netherlands Institute for War Holocaust and Genocide Suicides, has said.
Researchers have uncovered two pages of Anne Frank's diary masked over with brown paper that contain jokes and musings about sex, prostitution and contraception. He edited and published her writings in hiding after the war, making Anne Frank one of the world's most famous Holocaust victims.Anne Frank wrote the jokes on September 28, 1942, just three months after the family began their two-year stay at the hiding place.
Anne then attempts to explain sex to an imaginary person, using the information she's learnt from her father, a friend and books.
Five crossed-out phrases, four dirty jokes and 33 lines about sex education and prostitution were included on the two pages of her first diary, according to the Anne Frank House.
These new discoveries "bring us even closer to the girl and the writer Anne Frank", added Leopold.More news: German FA criticise Ozil, Gundogan for being 'manipulated'

On October 3, 1942, she wrote: "Daddy is grumbling again and threatening to take away my diary".
On July 6, 1942, they retreated into the secret annex of another home as the Nazis were rounding up Jewish families following their invasion of the Netherlands in 1940. She kept a diary throughout her time in hiding, and after her death, her father, Otto, published it in 1947.
At the time, Frank was 12 years old and curious about sex and relationships like other children her age.
Defending the decision to release the newly-found texts, the foundation said "over the decades Anne has grown to become the worldwide symbol of the Holocaust, and Anne the girl has increasingly faded into the background". Later, researchers realized the underlying text was partly visible and modern software could probably decipher it. Anne Frank and her sister Margot died at Bergen-Belsen in 1945.
Miss Frank wrote her diary while she and her family went in hiding for more than two years, in a bid to escape from the Nazis during World War II.
