School programs for learning-disabled students range from a modified or supplemental program in regular classes to placement in a special school, depending upon the severity of the disability. The field of learning disabilities is considered to have emerged as a separate discipline in 1947 with the publication of the book Psychopathology and Education of the Brain-Injured Child by neuropsychiatrist Alfred A.

The need to help students with these disabilities was first recognized on the federal level in 1958, when Congress appropriated $1 million to train teachers for the mentally retarded. Famous people considered to have had a learning disability include Winston Churchill, Thomas Edison, and Nelson Rockefeller.
