The Physharmonica is from the estate of Friedrich Wieck. (now in Schumann museum in Leipzig)

It was built in Vienna around 1825. Clara Wieck received a similar Physharmonica, built by Joseph Carl Fuchs (1789-1832) on the 10th of March 1828 as an improvisation and travel instrument. This was a forerunner of the later Harmonium. The wind is generated by the left pedal; the volume can be reduced during playing by opening a wind-release vent with the right pedal. A brass knob on the left side of the keyboard provides the same function. Marie Wieck sold the instrument to the Schumann collector Alfred Wiede in Weißenborn; he then made a gift of it to the Zwickau Schumann Museum on the 21st of April 1917.
