Holocaust survivor Tomi Reichental, who moved to Ireland in 1959, died on Sunday at the age of 90. He dedicated much of his life to giving talks in schools, colleges and across Ireland on the Holocaust, teaching younger generations about the horror of it. 

In the Irish Times this week, Alexandra Sen-fft wrote a piece about how it was her Nazi grandfather who sent Tomi and his family to a death camp, and how she and Tomi met in later in life. Alexandra spoke to Claire this morning.
