Description

Georg von Békésy (1899–1972) was a distinguished Hungarian biophysicist and Nobel laureate, recognized with the Nobel Prize in Physiology or Medicine in 1961 for his pioneering research on the physical mechanisms of hearing within the cochlea, the spiral-shaped cavity of the inner ear.

Békésy's investigations were pivotal in advancing the understanding of auditory perception. His most notable contribution, the place theory of hearing, proposed that different frequencies of sound activate distinct regions along the basilar membrane of the cochlea. This theory transformed the comprehension of how the ear processes sound and laid the foundation for subsequent studies in auditory neuroscience.

Through meticulous experiments employing innovative techniques such as micromanipulation and direct observation of inner ear structures, Békésy provided profound insights into cochlear function and the auditory system, unraveling the intricacies of human hearing. Beyond his scientific achievements, he made significant contributions to education and academic leadership, mentoring numerous students and researchers in biophysics and auditory physiology.

Depicts one of Georg von Békésy's pivotal discoveries: the transmission of sound waves through the cochlea of the inner ear. Within the cochlea's depiction, the inscription "GYÖRGY BÉKÉSY WAS AWARDED IN 1961 FOR THE DISCOVERY OF THE PHYSICAL MECHANISM OF STIMULATION IN THE COCHLEA OF THE INNER EAR" is inscribed in small letters and numbers. Surrounding the cochlea are markings indicating sound wave frequencies: "200 Hz, 400 Hz, 600 Hz, 800 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 3000 Hz, 4000 Hz, 5000 Hz, 7000 Hz, 20000 Hz."

Positioned on the left side, centered, are three lines representing the denomination, the inscription "FORINT," and the mintmark "BP." Along the edge, the inscriptions "HUNGARY" and the issue year "2022" are placed. On the right side edge, centered, the engraver's privy mark is included.
