A jazz musician named Teri Pall invented a version of the cordless phone in 1965 but could not market her invention, as its 2-mile (3.2 km) range caused its radio signals to interfere with aircraft communications. In 1968, she sold her rights to the cordless phone to a manufacturer who modified it for practical use.
Alexander Graham Bell (March 3, 1847 â August 2, 1922)[4] was an eminent Scottish-born scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone.[N 3] 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 life's work.[7]
