This "Jackie Robinson of jewish authors" is an interesting claim. In college I took a class on short fiction and the fiction of ubran jewish authors in the 40s and 50s was obviously a pet rock of the professor. We read a lot of Bernard Malamud and Philip Roth and people like that. But Herman Wouk's name was never mentioned. I guess he just wrote novels, not short fiction. I never knew he paved the way for those other guys.
He’s considered more a writer of popular fiction as opposed to literature.
