A Dictionary of Music and Musicians/Physharmonica
PHYSHARMONICA. A little reed organ invented in Vienna in 1818 by Anton Häckel, who intended it to be placed under the keyboard of the piano, to sustain the melody. It was increased in size and importance and by various improvements at length developed into the Harmonium. The name is used in Germany for a free-reed stop in the organ.
