Sam Krongold was born in Ostrowiec in 1920, son of Jonasz and Zysla  Krongold and was the youngest of his four siblings. In 1940, authorities forced Sam's family to transfer ownership of their factory and they were relocated to the Ostrowiec Ghetto.

In 1943, the Germans deported Sam to Skarżysko-Kamienna Labour Camp. In 1944, they transferred him to Buchenwald Concentration Camp, followed by Schlieben Concentration Camp, then to Theresienstadt Ghetto-Camp, where the Soviet Army liberated him in May 1945.

Sam married his wife Funia in 1946 and returned to Ostrowiec to operate his father's factory. After two weeks, a friend warned Sam about the dangers of staying in Poland. With his wife and surviving family members, Sam migrated to West Germany. In 1951, the family immigrated to Canada and settled in Toronto, where Sam opened a furniture business. Sam and Funia had two children.

Sam recorded his testimony in 1989 and passed away in 2018.
