Olga Lengyel

Olga Lengyel was a Romanian nurse and Holocaust survivor who wrote about her experiences in Auschwitz.

She was deported there in 1944 with her family, losing her parents, children, and husband.

As the sole survivor, she published "Five Chimneys" in 1947 to document the atrocities she witnessed.

Lengyel served as a witness in the Bergen-Belsen trial and dedicated her life to preserving the memory of Holocaust victims.

Her book is considered one of the earliest and most significant Holocaust memoirs, offering a detailed account of life in the concentration camps and the crimes committed there.
