Meyrowitz Otophone 1C

The Meyrowitz Otophone 1C was manufactured by E. B. Meyrowitz, Co., Inc. of New York, possibly as early as 1887. Devices similar to Otophones were still being listed in catalogues as late as 1928.

Emil Meyrowitz was an optician who also manufactured surgical instruments in addition to various non electric hearing aids.

The Otophone 1C weighed 2.7 oz. (76 g).

The Model 1 Otophones came in 3 sizes—A, B and C with C being the largest size.

Side view of the Meyrowitz Otophone 1C. The Otophone 1C stood 3¼" (8.3 cm) high and was 3⅞" (9.8 cm) front to back.

The Series 1 otophones consisted of a cone opening (bell), and a diaphragm earphone set at right angles.

To use, you held the earphone flat against your ear with the cone facing forward.

View of the Meyrowitz Otophone 1C showing the black earphone and brown bell.

Originally the whole Otophone was black, but because it was made out of vulcanite (hard rubber), over time, when exposed to the air, the sulfur in the vulcanite oxidized and changed the color to a coppery-brown shade.

The reason the front of the earphone remained black is because it was protected from the air by a tight-fitting leatherette cover, which obviously was kept in place most of the time. Note that from the edge of the cover onward the Meyrowitz Otophone 1C is discolored.
