It is also noteworthy that Scottish-born Alexander Graham Bell made many advancements for the deaf. His concern for them involved led him to pursue a method called "Visible Speech" a technique initiated by his father. This system involved teaching deaf students how to position their tongues, mouth, and lips for each phonetic sound. After Graham received a patent on his telephone, he continued his experiments in communication with the photophone--transmission of sound on a beam of light--as well as his experiments in medical research and in techniques of teaching speech to the deaf.
Bell also invented the Graphophone. By using an engraving stylus, controllable speeds, and wax cylinders and disks, the Graphophone presented a practical approach to sound recording. With the money that he earned from this invention, Bell continued his work for the deaf. In May 8, 1893, his thirteen-year-old prodigy, Helen Keller, took part in the ground-breaking ceremonies of the new Volta Bureau building, which is today an international center relating to the oral education of the deaf.
An innovator as well as an inventor, Bell succeeded his father-in-law as President of the National Geographic Society in 1898. While in this office, Bell transformed a small pamphlet sent out by the society into the graphically beautiful magazine that it is today.
