Since I'm not sure of the death location, I haven't checked. I do know he lived in LA for quite a while, but can't find anything there for him. There was another Harry Bloom involved in the movie industry, but I'm fairly sure that's not him.
I don't think his name would appear as Harold, but as something in Yiddish. I've yet to figure out the likely answer to that.
Family members will cofirm his existance, but nothing more.
