As usual l you are wrong Marconi was credited with inventing radio and developing it.
He got the Nobel prize for that not his commercial operation of it.
As usual you don't know the hystory. He invented and he was a pioneer of wireless telegraphy, (you wrote radio) exactly the same field of Nobel quotation.
"The Nobel Prize in Physics 1909 was awarded jointly to Guglielmo Marconi and Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy"
Jointly with another makes some difference? is it not a Nobel to him?
