It was Lewis Nixon who invented the very first sonar-type listening device in 1906. He was seeking a way of detecting icebergs. But the sonar was not "invented", its inventor was nobody, but developed through the years.Sonar had very humble beginnings, from crude instruments to advanced technology. (However, the natural sensory process cannot be invented, see bisonar or echolocation for that.)
