[The following provides links to various articles and sources which explicitly expose the lies and obfuscations of Holocaust denier Bishop Williamson. We hope they are helpful to you. My profound thanks to Dan Leshem and Maureen McLaughlin for helping prepare this material.]

1. Williamson says: “I believe there were no gas chambers."

This claim is one of several pillars of Holocaust denial. For an overview on the design, number, and operation of the gas chambers and some pictures. Click here or here.

Few expected very much of Franklin Roosevelt on Inauguration Day in 1933. Like Barack Obama seventy-six years later, he was succeeding a failed Republican president, and Americans had voted for change. What that change might be Roosevelt never clearly said, probably because he himself didn't know.

Herbert Hoover, the departing president, had left behind an economic cataclysm. Since the 1929 stock market crash the economy had been spiraling inexorably downward for more than three years. The country had always experienced episodic "panics" and "recessions," but nothing this bad. As Anthony J. Badger writes in FDR: The First Hundred Days, "Americans had never been there before."

Roosevelt's declaration that Americans had "nothing to fear but fear itself" was a glorious piece of inspirational rhetoric and just as gloriously wrong. Banks across the country had been failing for months and thousands more were on the brink as he...

Anniversaries are the last refuge of the journalist and 2009 is no exception. Happy 40th, then, to the Moon landings, felice quattro centesimo compleanno to Galileo's telescope, and glücklich vier Hundertstel Geburtstag to Kepler and his laws of planetary motion. One birthday boy gets two slices of cake, for Charles Darwin is 200 this year and his best-known book is 50 years younger. To look back on his life is to be astonished by his almost uncanny ability to predict the course of biology to the present day and beyond.

The Origin of Species is one of those tomes that everyone knows but nobody has read - but it is only one of Darwin's many works. They could, together, celebrate more than a dozen birthdays over the next several decades - and they deserve a few crumbs from the 2009 table as a reminder of how much they, too, set the agenda of modern science....

About 1 million people from around the world visit the Auschwitz memorial each year to commemorate the victims of the Holocaust. It's a significant number of people, who still come to the museum to get an idea of living and dying in this former antechamber of hell -- and to learn from history.

Memorial officials recently rang sounded an alarm, saying that the buildings are in danger of collapsing and that a lot of money is needed for their restoration. Germany reacted quickly and said that it would help out financially. And rightly so. More than six decades after the end of the war, it remains a duty for state and society to accept historic responsibility and keep the memory alive -- even if this becomes more and more difficult as the distance of time keeps growing and eyewitnesses die.

History books, museums, TV documentaries and movie films have to replace personal conversations. The ability to relate to the topic -- both in terms of time and emotions -- continues to...

If you are getting off a train while on your way to meet a contact in an historic part of Stuttgart, it is a good idea not to graze your right hand against a door hinge so hard that you lose most of the skin from your middle knuckle.

I know, because this is just what happened as I was struggling to reach an appointment with Christopher Dowe.

Luckily, he was very understanding when we met, and even helped to dress the wound, though I can't help wondering what went through his mind as he saw a flustered and cold British reporter wading through the snow with a suitcase in one hand and blood dripping from the other.

Dr Dowe works with the Baden-Württemberg Stauffenberg Association, a group aiming to maintain the memory of Colonel Claus von Stauffenberg.

The 36-year-old soldier, portrayed in Valkyrie by Tom Cruise, planted the bomb that so nearly killed Hitler on 20 July 1944, and perhaps...

It is minus 12 degrees on a Beijing dawn and a line of 32 soldiers raise their bayonets to a rising red flag. Perhaps a thousand pilgrims have gathered to express their national pride at Tiananmen Square, the sacred heart of Communist China.

Ahead is the Gate of Heavenly Peace, from where Mao proclaimed the new People's government about 60 years ago. Behind lies the Monument of the People's Heroes and a mausoleum for Mao's embalmed body. They are two monuments of history, frozen without context, in a city designed and continually remade to forget its past.

Geremie Barme's The Forbidden City tells how a million Red Guards ushered in the Cultural Revolution against all things old with chants previously reserved for the emperor - "wansui, wansui, wansui - may he live for 10,000 years". Mao waved to them from the gate.

In Tiananmen Square the old is erased and reborn. It pays to bring...

[Donald Ritchie, author of Reporting from Washington: The History of the Washington Press Corps, Our Constitution, and The Congress of the United States: A Student Companion, looks at how the Presidential Inauguration moved from the East Front of the Capitol to the West Front. Ritchie, who has been Associate Historian of the United States Senate for more than three decades, reveals that it was not Reagan’s decision.]

When Barack Obama took the oath as President of the United States on the West Front of the U.S. Capitol, more than one commentator attributed that location to Ronald Reagan, who in 1981 became the first president inaugurated there. Previously, presidents from Andrew Jackson to Jimmy Carter had been sworn into office on the Capitol’s East Front. Reading historical and symbolic significance into that switch, a historian writing in the Washington Post [January 18, 2008] asserted that “Reagan’s inaugural team took the extraordinary step of moving the entire...

There are unsettling ghosts of America past all about the National Mall. Hundreds of thousands of people will gather there Tuesday for the inauguration of the nation’s first African-American president. Three blocks from where Barack Obama takes the oath, there was once the Saint Charles Hotel, a popular accommodation on Pennsylvania Avenue before emancipation ruined business for slave traders. It proudly advertised that down below its first-rate restaurant, guests could avail themselves of six, 30-foot-long arched slave cells, replete with wall rings and shackles. The management promised: “In case of escape, full value for the Negro will be paid.”

A few blocks from there was the notorious Yellow House, a three-story brick slave market where trader William Williams prospered enough to purchase two slave ships of his own. Solomon Northrup, a free man from New York who was kidnapped into slavery, passed through on the block and eventually wrote a memoir. He recalled how “the...
