The answer that you're looking for is "Rabbi Johanan ben Zakkai."

However, there is a mistake in your question and its perceived answer. Rabbi Johanan did not found the Torah-academy in Yavneh. Rather, it had already existed, and he bolstered it with hundreds of additional disciples.

Answer 1

Generally speaking, English-language bibles translate the names of the characters in the Bible stores to their generally-accepted English equivalents.

Yohanan ben Zaccai

would appear in most Bibles as

John the Baptist

He can be found in all four of the Gospels.

Answer 2

Most Jews and Historians do not believe Yohanan ben Zakkai and John the Baptist are analogous persons. Yohanan ben Zakkai was a Jewish Rabbi who negotiated with Vespasian to preserve the Jewish Religious Authorities at Yavne during the Roman Siege of Jerusalem. John the Baptist was a simple, but intelligent man who took it upon himself to baptize people, as was Jewish custom in those days.
