Stumble Upon find

I was looking around for links to Denver Airport's Supposed Swastika runways, and found where someone had posted photos of the murals in Denver Airport. There was one a poem, very heartbreaking.

I was once a little child
who longed for other worlds.
But I am no more a child
for I have known fear,
I have learned to hate...
How tragic, then is youth
which lives with enemies,
with gallows ropes.
Yet, I still believe
I only sleep today,
that I'll wake up,
a child again, and
start to laugh
and play.

Below it gives a name which I can't make out, but it says it is authored by a 14-year old who died in 1943 in the death camp at Auschwitz.

If anyone knows the name of the author I would appreciate a comment.
