ethw.orgEdison proposed wireless telegraphy to meet the special needs of seafaring. In an 1885 patent application, Edison underscored the importance to safety if ships could communicate through dense fog by means of wireless telegraphy. Ships not only could crash on rocks hidden by dense fog, they could easily collide into each other as they came closer to shore. Ship-to-ship communication through the thick fog would have been heaven sent. Based on electrostatic induction, Edison’s patent did not offer a realistic solution to maritime communication. His patent, nevertheless, did lay claim to the idea of an aerial antenna whose rights Marconi felt compelled to buy in 1903.
