In 1919 Tad became deaf-blind when he contracted spinal meningitis and lost his sight and hearing at the age of 4. His father went before the South Dakota State Legislature and proved that despite being totally deaf and totally blind Tad was capable of learning; therefore, the State of South Dakota was responsible for his education according to the State Constitution at that time. Tad was sent to the Sioux Falls School for the Deaf and taught by Miss Sophia Alcorn. He learned to speak and to Alisten@ to people by placing his hand lightly on the speaker=s face and interpreting the lip movement, vibration, and muscle movements. Sophia Alcorn named this the Tadoma Method -- named for Tad and Oma Simpson, the first two people to use this method exclusively. Tad graduated high school from Perkins Institute for the Blind in 1933. He was the first deaf-blind person to graduate high school with a regular class at Perkins. His education there was such a positive experience that the Institute opened a deaf-blind department.
Tad remained a student throughout his life. He learned languages (German, French, Spanish, Esperanto, and more) and took correspondence classes from the Hadley School for the Blind in Illinois.
