Who invented Adderall?

I think it was L. Edeleano but I don't know for a fact

Hi! Amphetamine was first synthesized in 1887, by the German chemist L. Edeleano, the stimulant effects were not noticed. In the early 1930s, when amphetamine's CNS stimulant properties and use as a respiratory stimulant were discovered it was marketed as an inhaler for nasal congestion. At this time, medical professionals recommended amphetamine as a cure for a range of ailments-alcohol hangover, narcolepsy, depression, weight reduction, hyperactivity in children, and vomiting associated with pregnancy. The use of amphetamine grew rapidly because it was inexpensive, readily available, had long lasting effects, and because professionals purported that amphetamine did not pose an addiction risk. Oral and intravenous preparations of amphetamine derivatives, including methamphetamine, were developed and became available for therapeutic purposes. During World War II, the military in the United States, Great Britain, Germany, and Japan used amphetamines to increase alertness and endurance and to improve mood. Abuse began rising during the 1960s and 1970s with the discovery that the intravenous injection of amphetamines (particularly methamphetamine) produced enhanced euphoric effects with a more rapid onset than oral administration. Although structurally similar to amphetamine, methamphetamine has more pronounced effects on the CNS. Between 1986 and 1989, law enforcement and treatment admission professionals in Hawaii reported that abuse of a concentrated form of methamphetamine (known as "ice," "glass," and "crystal") was increasing.
