Anne Frank

Anne Frank's birthday was June 12, 1929. Her story - her courage, her torment, her humanity - remains an inspiration for all people and reminds us that the Nazi bestiality was as quick as to murder children as anyone else.

In her own words:

It's really a wonder that I haven't dropped all my ideals, because they seem so absurd and impossible to carry out. Yet I keep them, because in spite of everything I still believe that people are really good at heart.

The Holes in the Roofs of the Gas Chambers at Auschwitz-Birkenau: A forensic investigation proves their existence

"No holes, no Holocaust" has long been one of the denier community's favorite slogans. It refers to the holes in the roof of Kremas (crematoria) II and III at the Auschwitz-Birkenau extermination camp. Now a report entitled The Ruins of the Gas Chambers: A Forensic Investigation of Crematoriums at Auschwitz I and Auschwitz-Birkenau by Daniel Keren, Harry W. Mazal and Jamie McCarthy proves not only that the holes existed but shows where they are. This report first appeared in Holocaust and Genocide Studies, Oxford University Press, Volume 18, Number 1, Spring 2004, pages 68-103. and is reproduced with permission.

Holocaust Denial

We have a special page devoted to an examination of Holocaust denial and deniers.

Among other things, we offer a quick questions and answers page on revisionism and Holocaust deniers.

David Irving is a Holocaust denier residing in the UK who recently lost a lawsuit to Deborah Lipstadt. We now have an index organizing material about David Irving.

We also offer a pamphlet for those seeking a printed concise introduction to David Irving and his lies, entitled Who is David Irving?

(Over a year ago, David Irving called this pamphlet "lies" and "fiction." Although he constructed a special webpage to reprint it, and has corresponded with us several times, he has been unable to name even one error. In July 1998, he said he would respond - and after a long silence, in January 1999 decided not.)

CODOH (the so-called committee for open discussion of the Holocaust story) is one of the major disseminators of denial in the US. We now have a webpage devoted to addressing the challenge that they pose.

We have a letter from Joel Hayward regarding his change of views with respect to his Master's thesis.

Early in 2009, the Vatican rehabilitated four Bishops who had been consecrated by Archbishop Marcel Lefebvre 20 years ago. Since this had been done without Vatican approval, the Bishops were excommunicated. Not long after the rehabilitation had been announced by Pope Benedict XVI, it came to light that one of the Bishops - Richard Williamson - has expressed views consistent with those of Holocaust deniers and antisemites in a television interview aired just days before the Vatican decision was announced. A firestorm of controversy arose, which has been documented in the media, and need not be repeated here. The Bishop was ordered to recant his views (which he has yet to do). THHP member Harry W. Mazal has written a Response to statements made by Bishop Richard Williamson concerning the Holocaust from both the historical and scientific perspectives of Bishop Williamson's public statements.
