His mother Raisa was from Bessarabia. He helped found and has led the Sons and Daughters of Jewish Deportees from France (Association des fils et filles des déportés juifs de France) or FFDJF. It is one of the groups that has documented cases and located former German and French officials for prosecution such as Klaus Barbie, René Bousquet, Jean Leguay, Maurice Papon and Paul Touvier, who have been implicated in the deaths ofhundreds of thousands of French and foreign Jews during the Second World War. The Klarsfelds were among organised groups who filed cases decades after the war, sometimes as late as the 1990s, against such officials for their crimes against humanity. In the years before 1989 and the break-up of the Soviet Union, the Klarsfeld family frequently protested against the Eastern Bloc's support for the PLO and anti- Zionism. Recognition for their work has included France's Legion of Honour in 1984. In 1986, their story was adapted as an American television film starring Tom Conti, Farrah Fawcett and Geraldine Page. In 2008, a French television movie was made about them. On 1January 2014, the Klarsfelds' Legion of Honour ranks were upgraded: Serge became Grand officier. On 26 October 2015, the UNESCO designa- ted the Klarsfelds as "Honorary Ambassadors and Special Envoys for Education about the Holocaust and the Prevention ofGenocide"
