I remember the first time I saw the little brass plates tucked between cobblestones in the German town I grew up in – the street my grandmother had lived on for a large part of her life. I was a teenager, walking with one of my friends when they stopped us in our tracks; their small inscription forcing us to kneel to read them: Here lived Max Mayerfeld. Nanny Spiro. Leo Spiro. Frank Spiro – aged only 12 at the time of his death. Deported 1942 towards the East. Killed 1942 in Treblinka.
