YIVO Encyclopedia: https://yivoencyclopedia.org/article.aspx/baal_shem_tov: "(Yisra’el ben Eli‘ezer, 'the Besht'; ca. 1700–1760), healer, miracle worker, and religious mystic... founder of the modern Hasidic movement... in the 1730s, Yisra’el began using the title ba‘al shem or ba‘al shem tov (... meaning that he was a 'master of God's name,' which he could manipulate for theurgic purposes), denoting his skills as a healer—one Polish source refers to him as ba‘al shem doctor—and his general qualifications as a shaman, a figure who could mediate between this world and the divine spheres in an effort to help people solve their... problems."
