Intrigued by LSD's potential to "augment human intelligence," Doug Englebart, the father of the mouse, first took LSD with a group of engineers at the International Foundation for Advanced Study. Englebart and the other engineers were told that the drug would help them solve difficult technical problems. Englebart didn't get much of a creativity boost from LSD the first time he took it (he was given a very low dose), but the second time, he came up with an idea for a toy that would help potty train boys.
