Parts of Anne Frank's diary are written in ball point pen
Holocaust Deniers Say:
Parts of Anne Frank's diary are written in ball point pen which wasn't available until after the war.
Holocaust deniers argue:
David Irving, whom the High Court in London declared to be a Holocaust denier, racist and antisemite, has stated that parts of Anne's diary had been written in "ball-point ink" which did not become generally available until the early 1950s.1
The truth about whether some parts of the diary are written ball-point pen.
Anne wrote the body of her diary with a fountain pen - that is a pen that uses wet ink. The only significant traces of ball-point pen ink are confined to two loose scraps of paper put with the diary materials later (probably by Otto Frank). They are in a distinctly different hand from Anne's. When Otto Frank organized the books and papers after the war he numbered the pages partly in ball-point pen and partly in colored pencil.2
Anne wrote the body of her diary with a fountain pen. The only ball point pen ink traces are two loose notes written by someone else and put with the papers later and some page numbers written on the sheets during the compilation process.
