I want to know the answer to the following question:
Who founded what is known as the Baal Shem Tov?
All the background I'm provided with is that "In a practical sense, what distinguishes Hasidic Judaism from other forms of Haredi Judaism is the close-knit organization of Hasidic communities centered on a Rebbe (sometimes translated as "Grand Rabbi"), and various customs and modes of dress particular to each community.". Is that enough to answer the question?
