RADIO

Now Hear This: A campaign to declare Nathan B. Stubblefield as the inventor of radio will be launched at a news conference this morning in Pasadena. Stubblefield’s grandson Troy Cory and attorneys will open a strongbox believed to contain financial records, proof of demonstrations and original patents of the inventor who died in 1928. Affidavits in 1892 tell of Stubblefield’s first successful wireless voice transmission on land. Marconi, often cited as the father of radio, broadcast his first wireless Morse code dot-dash in 1896.
