Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a Scottish-born scientist, inventor, engineer, and innovator who is credited with inventing and patenting the first practical telephone. He also founded the American Telephone and Telegraph Company (AT&T) in 1885. Bell's father, grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's work. His research on hearing and speech led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876. Bell considered his invention an intrusion on his real work as a scientist. Other inventions included work in optical telecommunications, hydrofoils, and aeronautics. The document contains records of familial occurrences of deafness and marriage statistics. Tables indicate that within schools for the deaf many students had the same family name; it was considered highly probable that a considerable proportion of deaf mutes belonged to families containing more than one such person. Of 5,823 deaf mutes from various parts of the county, 29.5% were known to have deaf and mute relatives. Records from two institutions showed that about one half of the students born before 1840 had married; of 1,089 from five schools who had married, an increased proportion had married other deaf mutes. Indications were found that a hereditary tendency toward deafness, as indicated by the possession of deaf relatives, was a more important element in determining the production of deaf offspring, and that the proportion of deaf mute children born to deaf mutes was greater than the proportion born to the people at large. Other information included charts, graphs, and family trees. Condition: Fair.
