David Tannenberg, born on March 21, 1728, in Berthelsdorf, Germany, was a prominent Moravian organ builder who immigrated to Pennsylvania. He is recognized as one of the most significant American organ builders of the 18th century. After arriving in America in 1749, Tannenberg became involved in the Moravian community's construction activities and later specialized in organ building. He learned the craft from Johann Gottlob Klemm and, following Klemm’s death, Tannenberg built over forty organs across various states including Pennsylvania and North Carolina. His organs, admired for their craftsmanship, are still in use today. He also built pianos and harpsichords, though none survive. Tannenberg passed away on May 19, 1804, in York, Pennsylvania.
