born June 3, 1899, Budapest, Hung.
died June 13, 1972, Honolulu, Hawaii, U.S.
Hungarian-born U.S. physicist and physiologist.
He immigrated to the U.S. in 1947 and taught at Harvard University in 1947–66. He discovered that sound vibrations travel along a membrane in the cochlea in waves, peaking at different places, where nerve receptors determine pitch and loudness. His research resulted in greatly expanded understanding of the hearing process, partly through instrumentation Békésy had helped design, and the differentiation of forms of deafness, which permitted the selection of proper treatment. He received a 1961 Nobel Prize for Physiology or Medicine.
