The illustrations on the reverse of the note include Bell's face in profile, his signature, and objects from Bell's life and career: users of the telephone over the ages; an audio wave signal; a diagram of a telephone receiver; geometric shapes from engineering structures; representations of sign language and the phonetic alphabet; the geese which helped him to understand flight; and the sheep which he studied to understand genetics. [183], Bell died of complications arising from diabetes on August 2, 1922, at his private estate in Cape Breton, Nova Scotia, at age 75.

Bells other major undertaking was the development of an electrical bullet probe, an early version of the metal detector, for surgical use. [119][120] Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. 1876 Telephones Facts About The Most Important Invention Ever Made - Kidadl At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere.
