Magnus Harmonica Corporation Explained

The Magnus Harmonica Corporation (originally the International Plastic Harmonica Corporation) was founded in 1944 in New Jersey by Danish immigrant Finn Magnus (1905–1976).^[1] First supplying American troops in World War II, and later marketed to children and other beginners, the company's harmonicas (as well as its accordions, bagpipes, and mechanical reed organs) used a then-unique molded-plastic reed comb. The styrene-based plastic construction resulted in lower cost, greater durability, and a distinct sound compared to other free reed aerophones with metal reeds.^{[2] [3] [4] [5] [6]}

In 1958, Magnus joined with television salesman Eugene Tracey, and their company went on to sell millions of inexpensive electric chord organs and song books^{[7] [8]} until the late 1970s under the name Magnus Organ Corporation. Early Magnus Chord Organs were either laptop or tabletop models, with some of the later models having integrated legs and a lighted music stand.^[9] At its peak, Magnus employed over 1,800 workers in Linden, New Jersey, including a "mother's shift" during school hours and a "work release" program for non-violent inmates of the nearby Rahway State Prison.

After Magnus and Tracey retired, the publishers of World Book Encyclopedia ultimately acquired the Magnus sheet music catalog and ceased production of Magnus instruments.
