1948 according to this site: http://www.childdevelopmentinfo.com/disorders/medications.htm

"Stimulant Drugs
Overview
The history of stimulant drug use dates back to the discovery by Bradley in 1937 of the therapeutic effects of Benzedrine® on behaviorally-disturbed children. In 1948, Dexedrine® was introduced, with the advantage of having equal efficacy at half the dose. Ritalin® was released in 1954 with the hope that it would have fewer side effects and less abuse potential. Although initially used as antidepressants and diet pills, stimulant drugs are not used for these purposes today.

In 1957, Laufer described the "hyperkinetic impulse disorder," which he believed was caused by a maturational lag in the development of the central nervous system. He asserted that stimulant drugs were the treatment of choice for this disorder and postulated that they acted by stimulating the midbrain, placing it in a more synchronous balance with the outer cerebral cortex. This was an oversimplification but the exact mechanism of action of these drugs is still unknown."
