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.
The real inventor of the telephone, Meucci (1808â1989), had been working in Cuba in the 1830s, developing methods for treating illnesses using electric shocks, when he discovered the ability of sound to travel through electrical impulses. He later moved to Staten Island to follow up on his discovery.
