Who invented the first otoscope

An Otoscope, or an ear speculum, is a device that assists doctors in examining the nasal and aural ear passages of the patient. It consists of a long handle, and on the head is a magnifier that the doctor peers through, and a light to better see the area he or she is inspecting.

The end of the Otoscope is used to examine the patient without damaging the ear or nasal canal. Whenever a patient comes into an office complaining of blockage or pain within the ear or nose, the Otoscope is the first thing the doctor reaches for. While most patients are pretty familiar with what the Otoscope does, few likely know the history of the tool. At that time, French physician and surgeon Guy de Chauliac envisioned a tool that could help diagnose patients complaining of ear or nose pain.

With this instrument he was the first to see the retina of a living human.

As means of illumination he used small panes of glass similar to cover-glasses which were introduced into the common visual axis of the observer and the subject at such an angle that light from a lamp was reflected into the subject's eye while the observer inspected the subject's retina through the glass and an appropriate lens. He recommended this type of illumination also for otoscopy. His invention was at once acclaimed throughout the world and opened completely new opportunities in ophthalmology.

The slanting panes of glass, however, were not the ideal solution for illumination.
