Binaural beats
Heinrich Wilhelm Dove (18031879) discovered binaural beats in 1839 and published his findings in the scientific journal Repertorium der Physik. While research about them continued after that, the subject remained something of a scientific curiosity until 134 years later, with the publishing of Gerald Oster's article "Auditory beats in the brain" (Scientific American, 1973). Oster's article identified and assembled the scattered pieces of relevant research since Dove, offering fresh insight (and new laboratory findings) to research on binaural beats.
