The Jehmlich Orgelbau Dresden GmbH is an organ building company that was founded in 1808 in Cämmerswalde in the Erzgebirge region by the three brothers Gotthelf Friedrich, Johann Gotthold, and Carl Gottlieb Jehmlich. The unique feature of being the world's oldest organ building company that has always remained in family hands was officially confirmed in 2008. Today, the company is based in Dresden.

It all began for the Jehmlichs in Neuwernsdorf in the Erzgebirge. In a newspaper lexicon from 1820, there is mention of the first generation of organ builders Jehmlich in the notices about Neu-Wernsdorf or Neuwarnsdorf:

"Moreover, I also point out the top house in the village, not so much because of its Dutch-style architecture, but because it is the residence of the mechanics and organ builders, the brothers Gämlich, who are distinguished by eminent talent. They produce, without having received any formal training, grand pianos with flute works of special quality, instruments and machines of all kinds, and in 1818 they also completed a very good organ in Lauenstein..."
