Juan José Lopez-Ibor (Sollana, Valencia, 22 April 1906 – Madrid 1991) was a Spanish psychiatrist.
In the 1960s, during the Franco dictatorship, López-Ibor performed lobotomies and electroshock therapy on psychiatric patients to "cure" homosexuality.
The house had about thirty rooms, all of them with "special plugs" to connect the "electroshock", which the psychiatrist applied without the consent of the patient or the family.
After an operation on the lower lobe of his brain he shows disorders in memory and eyesight, but he is slightly more attracted to women".
In the same year, he was among the first to report that the drug clomipramine was effective in treating obsessive-compulsive disorder.
