From organ building the first independent instruments with reeds were built around 1810. A decisive step in the development of this instrument was taken by Anton Haeckel from Vienna with his Physharmonika (in the picture a comparable later successor).

In 1821 A. Haeckel had patented asymmetrical reeds for this new type of instrument, which sounded only in one wind direction, but had a much better sound quality.
