Who Invented the Cordless Phone

The cordless telephone is a communication device with a wireless handset and a base station. The phone communicates with the base station via radio signals. The base station connects the cordless phone with the telephone line via a plug in attachment. Cordless phones require a power outlet to charge the rechargeable battery inside the wireless handset. This type of phone is now common in most homes where a fixed phone line is connected. The cordless phone allows greater range of mobility while speaking on the telephone. So who invented this modern marvel? Read this article to get the answer.

Who Invented the Cordless Phone?
The first cordless phone model was developed by a Jazz musician named Teri Pall. In 1965 she invented a version of the cordless phone with a range of two miles. It operated using low radio frequencies. Unfortunately she could not sell her invention because the radio signals interfered with aircraft. She sold her idea and rights for the cordless phone to a manufacturer who could modify it for practical use.

The cordless phone was further developed by George Sweigert, an amateur radio operator and inventor from Cleveland, Ohio. In 1966 he submitted a patent for a cordless phone (“full duplex wireless communications apparatus”) with The U.S. Patent and Trademark Office and was awarded the patent in 1969. It was further developed by Douglas G. Talley and L Duane Gregory during the early 1970’s so that it connected the handset with the base and included the tones for connection and disconnection. In the 1980’s a number of electronic manufactures begin to sell the cordless phone to the general public.
