He moved in with his uncles and opened a candy shop with one of them in the city Lodz, in central Poland. But then Nazis invaded Poland in 1939, marking the beginning of World War II and Kristal was moved to a ghetto in the city with his wife, Chaja Feige Frucht, and their two children.
His children died in the ghetto and he and his wife were sent to live in the German Nazi concentration camp of Auschwitz, where she died.
Kristal survived the ordeal and moved permanently to Israel in 1950 with his second wife, Batsheva, with whom he had a further two children.
Last year, Kristal made headlines after finally getting to celebrate the bar mitzvah he missed out on in 1916. With his mother dead and his father drafted into the Russian army, there was no one for the boy to celebrate with.
Instead, Kristal was able to celebrate his bar mitzvah and 113th birthday with his two surviving children, nine grandchildren and 30 great-grandchildren, The New York Times reported.
“My father is a religious man, and it was his dream his whole life to have a bar mitzvah,” his daughter Shulamith Kristal Kuperstoch, told the Times. “It was a miracle after everything that he has been through in his life. What else can you call it?”
In March of 2016, the Guinness World Records officially named him the world’s oldest man.
“There have been smarter, stronger and better looking men then me who are no longer alive,” he told the Guinness World Records at the time. “All that is left for us to do is to keep on working as hard as we can and rebuild what is lost.”
Kristal was one month away from celebrating his 114th birthday. He is survived by his two younger children and his many grandchildren and great-grandchildren.
