You can hear Avram's Journey on BBC Radio 5 Live from 20:00 BST on Tuesday, 29 May.
Avram Grant's story is an incredible one. We know him as the quietly spoken man who took Chelsea to within a John Terry penalty of the Champions League title in 2008.
We know him as the boss at West Ham and the man who gave the passionate speech to Portsmouth fans on the brink of relegation and administration in 2010.
His own story - the son of a Polish Jew who married the daughter of an influential Iraqi lawyer who was forced to flee to Israel - is remarkable, but the history of his family is as rich as it is tragic, as heart-warming as it is heart-breaking and as inspiring as it is dark.
Grant was aware his father had survived the Holocaust, but knew very little of his previous life until an unforgettable night as a teenager in Tel Aviv.
