Harold Hillman

Harold Hillman is a British scientist and an expert in the neurobiology of execution methods.

Hillman caused controversy in biological fields with his insistence that structures seen in cells under the electron microscope were little more than artefacts. He maintained that up to 90 percent of the brain is made up of "a fine, granular material that is virtually liquid" and that the brain only has two cell types, as opposed to four.

Mainstream scientists maintained that as fixation techniques have been compared with other analysis techniques, and that there is no explanation for why all the different techniques should produce identical artifacts.

Hillman's main field was neurobiology and resuscitation, in which his work was largely uncontroversial.

Hillman was a founder member of Amnesty International, and later produced research for the charity.

Hillman was Reader in Physiology at the University of Surrey from 1965 until 1989, when he took early retirement.

In 1997 he was awarded the Ig Nobel Peace Prize for his report "The Possible Pain Experienced During Execution by Different Methods."
