Miller Hutchison

Miller Reese Hutchison (1876–1944) was a electrical engineer and inventor. He
invented the first electrical hearing aid, called the Acousticon (below). His interest
in a hearing aid stemmed from a childhood friend who was deaf from scarlet fever.

Hutchison attended attended classes at the Medical College of Alabama to study 
the anatomy of the ear. In 1905 he turned over the rights for the Acousticon to 
Kelley Monroe Turner (shown below). Turner improved hearing aids, such as 
adding a volume control.
