Robert Rietti with tales of individual survivors of the Holocaust, when countless millions of Jews, Polish Catholics, gypsies, Serbian Orthodox Christians, German political or religious opponents, or the handicapped, as well as Russian prisoners of war, died in concentration and transit camps that stretched across Europe.
But what of those who survived? These are some of their stories.
Robert Rietti, the veteran actor, author, broadcaster and maestro of the art of film dubbing, was born in London in 1923.
The Riettis' were an ancient Italian Jewish family, who lived for many years in Ferrara and in fact had links with Queen Victoria's Prime Minister, Benjamin Disraeli, whose grandmother was Rebecca Rietti.
Early in the 20th century, Robert's father arrived in Britain to raise his family, while keeping his Italian citizenship and his strong Jewish faith.
In turn, Robert's son now lives in New York, where he is a Rabbi.
