A Dutch court today sentenced a Polish-Canadian man to two months in prison for projecting a laser message at Anne Frank’s home in Amsterdam, implying that the teenager’s famous Holocaust diary was a forgery.

The court did not follow the prosecution’s proposal that 42-year-old Robert B. be sentenced to six months in prison. The defendant will not be sent to prison since he has already served his sentence while in custody.

The 42-year-old was arrested after laser-projecting the message “Anne Frank, Inventor of the Fountain Pen”, misspelling her name. He implied in this way that the diary is fake because some of its pages are written with a pen that came into use after World War II.

THE theory this began to circulate when many were found pageswritten with a fountain pen, among Anne Frank’s papers in the 1980s. But it turned out that they had been accidentally left by a researcher some 20 years earlieraccording to Dutch media.

The court ruled that the message shown at the Anne Frank house-museum “crossed the limits of society’s tolerance”.

“To suggest that Anne Frank invented the fountain pen calls into question the authenticity of her diary. Given the enormous importance of The Diary of Anne Frank to the memory of the Holocaust, all of this can be considered a kind of revisionism,” the court explained in its reasoning.

Against Robert V. the management of the museum and the Center for Information and Documentation for Israel (CIDI) had appealed.

The Jewish teenager and her family hid for two years in a hidden part of this house during the Nazi occupation of the Netherlands. They were arrested in 1944. Anna and her sister died in the Bergen-Belsen concentration camp in 1945. Her diary, later found by the family’s sole survivor, her father Otto, is one of the most important accounts of the Holocaust and has sold nearly 30 million copies.
