Primo Levi, an Italian Jewish chemist, survived ten months of incarceration in Auschwitz concentration camp prior to its liberation in January 1945. He eventually made his way back to Italy. After his retirement from managing a chemical factory in 1977, he became a full time writer.
Naturally enough, his poems were influenced by his experience of Auschwitz. Many address that experience directly.
The piece I have chosen, though, is an exception. I'm sure any poet would relate to it. (Because the poems in this volume are dated, we know it was written fairly late in his life.)
Not many of his poems can be found online, but there are some at this link. At PoemHunter there are poems and prose quotations, for which he ia also famous. And here is another poem and a comprehensive article.He also wrote novels, short stories and essays; check out his Amazon page. He was interviewed in 1985 by Paris Review.
He is widely supposed to have committed suicide by jumping over the railing of the staircase outside his fourth floor apartment. I prefer the more recent opinion that, being elderly and subject to dizziness (which was known about him), he fell accidentally.
