Holocaust survivors and relatives of those killed have been speaking at memorial events in the West Midlands.
Sir Jonathan blamed prime time TV and best-selling books
Gabor Hirsch, 78, a survivor from the Auschwitz-Birkenau concentration camp, spoke at Wolverhampton University as part of Holocaust Memorial Day.
Before his talk, he said it was "important to remember" so young people would "try to avoid that something like that should happen again."
A multi-faith service at the Cenotaph in Wolverhampton has also been held.
Mr Hirsch weighed just over four stone (25.4 kg) when he was freed from the concentration camp, at the age of 15.
He said: "Our block or barracks was maybe about 300 metres away from the crematorium.
"We saw the chimneys, we saw the flames and we were told 'these are bakeries'".
At Wolverhampton's Cenotaph, the city's mayor, Councillor Trudy Bowen, as well as representatives of different faith communities, laid wreaths in memory of victims of the Holocaust.
This year, the national ceremony to mark Holocaust Memorial Day was being held in Liverpool.
Survivors and religious leaders were among those at the Philharmonic Hall, in the European Capital of Culture.
It was to mark the 1945 liberation of the Auschwitz-Birkenau concentration camp and victims of other atrocities were also being remembered.
More than 2,000 schools across the UK were also expected to hold events to mark the day.
