5/5 Emancipation was an important part of Jewish history. Segregated for hundreds of years, Jews were integrated and assimilated into European society. But, because of the Holocaust, most of these ghosts have been forgotten, because the community that might have remembered them no longer exists. Michael visits Vienna where in the early 20th century, Jews made up nearly half of the population but today they have virtually disappeared. Rachel Whiteread's Holocaust memorial pays tribute to these Austrian Jews. Michael also tells the ghost story of poet, Ludwig August Frankl. (Rpt).
