Johann Georg Stein, born on July 18, 1712, in Berlstedt and passing on November 16, 1785, in Lüneburg, was a notable German organ builder, distinct from a namesake instrument maker in Augsburg. His upbringing in Berlstedt, a town with a tradition in organ building, was instrumental to his career. The most influential organ builders from his region, Johann Georg Schröter and Franciscus Volckland, were also from Berlstedt, with Schröter being Stein's uncle and mentor. This relationship significantly shaped Stein's craftsmanship, evident in the similarities between his and Schröter's organ works.

Stein's professional journey began in Erfurt, where he trained under Schröter. By around 1745, he established his workshop in Uelzen, where he constructed a 32-register organ in St. Marien Church, his first documented work. This project earned him acclaim and helped secure further commissions in the area. In 1758, he moved to Lüneburg to take over the workshop of the late Johann Matthias Hagelstein, where he continued to build and maintain organs, including those in Lüneburg's main churches. His work was influential in blending the Thuringian organ-building style with the local traditions of northern Germany, marking a significant contribution to the musical landscape of the region. Two of his sons followed in his footsteps, continuing his legacy in organ building. Notably, only a few of Stein's instruments survive today, with the organs in Warlitz and Trebel being restored and preserved.
