∙ 11y agoActually, they were invented in different places. Thomas Edison is credited with inventing the light bulb, and he had a lab in Menlo Park, New Jersey as well as offices in New York and elsewhere. There are several people who claim to have invented the telegraph, but most American history books credit Samuel F.B. Morse; born in Massachusetts, he did some of his experiments in New York, New Jersey, and Washington DC. As for radio, it was developed in Europe by Guglielmo Marconi (some sources credit other inventors, like Nikola Tesla), and other experiments were done by Canadian Reginald Fessenden in Brant Rock, Massachusetts.

Where was the the light bulb invented?
The light bulb was invented in England in 1809 by Humphry Davy. I hope this helps you find what you are looking for! In England by Joseph Wilson Swan as Thomas Edison was inventing the light bulb in the US New Jersey is the state that the electric light bulb, radio, telegraph and submarine were all invented at. New Jersey is the state that the electric light bulb, radio, telegraph and submarine were all invented at. people often say it was invented in America by Thomas Edison this is in fact incorrect, he patented it in 1862 but was served with a court order in 1882 by Joseph swan for copyright infringement, Joseph swan patented it in 1861 a year before Thomas Edison, but the design was poor so he redesigned it and acquired a second patent in 1878. it is widely thought that Edison invented the build in 1879 but Swan had already been installing them a year earlier and he founded the Swan electric company in 1881. Edison in fact only improved on the design already patented, Edison and Swan later merged to become Edison and Swan United company So the short answer is: it was invented and patented by Joseph Swan in the UK!
