Johann Jakob Quandt (Lithuanian: Jonas Jokūbas Kvantas; 27 March 1686 in Königsberg – 17 January 1772 in Königsberg) was a German orthodox Lutheran theologian, and professor of theology in Königsberg. He opposed Pietism, but sympathized with Wolffianism.[1] He is known for sponsoring the first complete translation of the Bible into Lithuanian, the Quandt Bible of 1735.[2] He was also a librarian of the Königsberg Public Library (first librarian, 1714–18).
He was considered an excellent preacher. Frederick the Great called him the best preacher he knew. In 1743 he published a hymnal in response to Georg Friedrich Rogall's Pietist hymnal.[3]
