This is a timeline of important Jewish rabbis from the 900s to the 1400s. And another timeline from the 1400s to the 1900s.
All of them wrote in Hebrew.
But tell me more about how Hebrew was dead before modern Zionism.

I didn't see Kook on the list and from the 30's - 70's Heschel wrote in Hebrew. His Torah Min HaShmyim is a masterpiece that was not translated into English until 2005
