* If you mean books written in the Hebrew language: Then the answer is many different people, over a long period of time. This includes:
* Ancient Hebrew authors: The authors of the Hebrew Bible (Torah, Prophets, Writings), who lived from around the 8th century BCE to the 2nd century BCE.
* Medieval Jewish scholars: Rabbi Moses Maimonides (Mishneh Torah), Rabbi Judah HaLevi (Kuzari), and many others.
* Modern Hebrew writers: S.Y. Agnon, Yehuda Amichai, Amos Oz, David Grossman, and countless others.
* If you mean books written about Hebrew culture, language, or religion: This is a broader category, and includes writers from both Jewish and non-Jewish backgrounds. Some examples include:
* Biblical scholars: From across the world, who study the Hebrew Bible and its history.
* Linguists: Who research the Hebrew language and its evolution.
* Historians: Who focus on Jewish history and culture.
Therefore, there isn't a single "author" of Hebrew books, but rather a vast and diverse group of individuals who have contributed to this literary tradition over centuries.
