Through Aluminium, Non-fiction and Mesh

"Tin foil" is a common misnomer for aluminium foil in English-speaking countries; packaging metal foil was formerly made out of tin before it was replaced with aluminium.

Origin

A common delusion in schizophrenia is that others are influencing the sufferer's thoughts. James Tilly Matthews in 1797 complained of a machine he called an "Air Loom" influencing him, becoming one of the first documented cases. The common delusion was characterized in depth in the 1918 work On the Origin of the "Influencing Machine" in Schizophrenia. Some people – modernly called "Tin Foil Hatters" – have a belief that such hats prevent mind control by governments, spies, mobsters, corporations, extraterrestrial, or paranormal beings that employ ESP or the microwave auditory effect. People in many countries who believe they are "targeted individuals", subject to government, corporate, or criminal spying or harassment, have developed websites, conference calls, and support meetings to discuss their concerns, including the idea of protective headgear.

An early allusion to an "insulative electrical contrivance encircling the head during thought" occurs in the unusual 1909 non-fiction publication Atomic Consciousness by self-proclaimed "seer" John Palfrey (aka "James Bathurst") who believed such headgear was not effective for his "retention of thoughts and ideas" against a supposed "telepathic impactive impingement". Vice Magazine writes that the tin foil hat in popular culture "can be traced back in a very weird and prescient short story written in 1927 by Julian Huxley" titled "The Tissue-Culture King," wherein the main character uses a metal hat to prevent being mind controlled by the villain scientist. Over time the term tin foil hat has become associated with paranoia and conspiracy theories.
