Well, to make a long story short, Isaac Bashevis Singer was Jewish!
Since Isaac Bashevis Singer's mother was Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him Jewish. His father was Jewish too.
Isaac Bashevis Singer was born on November 21, 1902 in Poland.
He was a leading figure in the Yiddish literary movement, writing and publishing only in Yiddish, and was awarded the Nobel Prize in Literature in 1978. He also was awarded two U.S. National Book Awards, one in Children's Literature and one in Fiction.
