Georg von Békésy (Békésy György) (June 3, 1899 – June 13, 1972) was a Hungarian biophysicist born in Budapest.
In 1961, he was awarded the Nobel Prize in Physiology or Medicine for his research on the function of the cochlea in the mammalian hearing organ. The decision of the prize committee had been controversial from the beginning, and research of the past three decades revealed that von Békésy’s main conclusions were in error.

The decision of the prize committee had been controversial from the beginning, and research of the past three decades revealed that von Békésy’s main conclusions were in error.
Békésy developed a method for dissecting the inner ear of human cadavers while leaving the cochlea partly intact. By using strobe photography and silver flakes as a marker, he was able to observe that the basilar membrane moves like a surface wave when stimulated by sound. Because of the structure of the cochlea and the basilar membrane, different frequencies of sound cause the maximum amplitudes of the waves to occur at different places on the basilar membrane along the coil of the cochlea.
He concluded that his observations showed how different sound wave...
