Rabbi Yoel Shurin – the Poltava Illui – was a talmid of the Netziv and the Rosh Yeshiva of yeshivas Ohr Torah.
I found this article about the Poltaver Illui in the Yiddishe Licht.
And here in the publication Beis Yaakov.
Also, a קשה he asked in בבא קמא is brought in אבן האזל.
I have previously posted about him here.
