Some other charismatic and influential people with chiddushim were Moshe Rabbeinu, Yehoshua, Dovid HaMelech, Ezra HaSofer, Rabban Shimon Ben Yochoi, Rashi, Rambam, Rabbeinu Gershom, the Yaavetz, the Baal Shem Tov, the GRA and the Chofetz Chaim.
Chareidim do not follow any specific teachings of any specific Rebbi, nor do they believe in any specific values not already in the Torah. Chasidim follow the specific teachings of the Baal Shem Tov and his disciples; Telzers follow the teachings and Minhagim of the Telzer Yeshiva; the Mussar movement was started by Rav Yisroel Salanter – but “Chareidi”? There was no beginning to “Chareidism” except on Har Sinai; no particular person whose teachings they follow except Moshe Rabbeinu, and no particular Minhagim they perform.
