1912- 1913
Mr Rene Rondeau has done a great deal of research on the school phonograph and located
23 examples worldwide. This particular machine is unique, as it has unusual panels.
There is no Edison logo on the front. Probable one of the prototype machines. The
Edison School Phonograph was the last outside horn phonograph made by Edison, released
in December 1912 and discontinued in 1914. Mechanically it is identical to the Edison
Opera, however instead of the Opera's wooden cabinet and horn, the School Phonograph
was has a black-painted cast iron body with a metal horn (the better to withstand
the rigors of use among young school children). Like the Opera, the reproducer is
fixed in position and the record moves underneath it. The cast iron stand has casters
allowing it to be moved among different classrooms, and has racks to hold a set
of special educational cylinders. It was a resounding sales flop, and only 26 are
known to exist today.
