Delgado is known pretty much exclusively for his pioneering work on "mind control", as shown here, but it goes far beyond that.

First, one might think that he was just a guileless scientist pushing back the frontiers without sufficient consideration of the consequences. Nope, he was a villainous madman:

PSYCHOCIVILIZATION AND ITS DISCONTENTS: AN INTERVIEW WITH JOSÉ DELGADO (Cabinet Magazine, Spring 2001)

In 1972, an article citing Delgado’s views was presented at Congress’s MK-Ultra hearings:

We need a program of psychosurgery for political control of our society. The purpose is physical control of the mind. Everyone who deviates from the given norm can be surgically manipulated. The individual may think that the most important reality is his own existence, but this is only his personal point of view. This lacks historical perspective Man does not have the right to develop his own mind. This kind of liberal orientation has great appeal. We must electrically control the brain. Some day armies and generals will be controlled by electric stimulation of the brain.

Second, it will surprise exactly no one to find we can place him firmly and explicitly with the transhumanists.

Brain Researcher José Delgado Asks— ‘What Kind of Humans Would We Like to Construct?’ (NYT 11/15/1970)

“The human race,” he says, “is at an evolutionary turning point. We're very close to having the power to construct our own mental functions, through a knowledge of genetics (which I think will be complete within the next 25 years); and through a knowledge of the cerebral mechanisms which underlie our be havior. The question is what sort of humans would we like, ideally, to construct?” He smiles. “Not only our cities are very badly planned; we as human beings are, too. The results in both cases are disastrous."

Good riddance to a monster, Jose Delgado.
