An extremely detailed summary of the book The Invisible Rainbow: A History of Electricity and Life by Arthur Firstenberg.
The Invisible Rainbow: A History of Electricity and Life
Detailed Summary
Overview
The Invisible Rainbow: A History of Electricity and Life by Arthur Firstenberg is a historical and scientific narrative that examines the relationship between electricity and biological life. The central thesis of the book is that electrical technologies introduced since the eighteenth century have had profound biological and ecological effects that are largely unrecognized by modern science and medicine.
Firstenberg argues that the Earth historically existed within a narrow natural electromagnetic environment dominated by visible light and weak natural electrical fields. According to the book, the rapid expansion of artificial electricity—beginning with telegraph systems and continuing through modern wireless technologies—introduced powerful electromagnetic fields that may influence living organisms in ways not yet fully understood.
The book combines historical records, early electrical experiments, medical observations, and ecological examples to argue that electricity interacts with life at fundamental biological levels.
Structure of the Book
The book is divided into two main parts.
Part I — From the Beginning
Historical exploration of electricity and early biological experiments.
Part II — To the Present
Analysis of modern technologies and their potential biological consequences.
Prologue: The “Invisible Rainbow”
The prologue introduces the central metaphor of the book.
The visible rainbow represents only a small portion of the electromagnetic spectrum. Historically, life evolved primarily within the range of natural light and weak atmospheric electrical phenomena.
The author argues that modern technology has dramatically expanded the electromagnetic environment. Artificial sources now include:
- Power grid frequencies
- Radio transmissions
- Radar systems
- Microwave communications
- Wireless technologies
The prologue suggests that many modern diseases emerged during the same historical period when large-scale electrification occurred. Examples cited include:
- Anxiety disorders
- Influenza epidemics
- Diabetes
- Heart disease
- Cancer
The book proposes that the biological impact of electricity has been historically overlooked because scientific research largely focused on electrical engineering rather than biological effects.
Part I — The Early History of Electricity
1. Captured in a Bottle
The first chapter recounts the discovery of stored electricity through the Leyden jar experiment in 1746.
Scientists including:
- Pieter van Musschenbroek
- Ewald Georg von Kleist
- Jean Nicolas Sébastien Allamand
demonstrated that electrical charge could be stored in a glass container.
The discovery triggered a wave of fascination known as “electromania.”
Public demonstrations included:
- Electrified chains of people
- Electrical parlor games
- “Electric kisses”
- Public experiments on animals
Despite warnings about possible dangers, enthusiasm for electricity rapidly spread across Europe and America.
Electricity also began to be used medically. Doctors and experimenters applied electrical shocks and currents in attempts to treat various diseases.
Medical uses included treatments for:
- Paralysis
- Nervous disorders
- Rheumatism
- Deafness
- Depression
These practices became widespread in the eighteenth century.
2. Electricity and Early Medicine
During the eighteenth and nineteenth centuries, electricity was commonly used as a medical therapy.
Doctors employed several techniques:
- Electric bath: The patient accumulated static charge while insulated from ground.
- Electric wind: Discharging electrical fields onto specific body parts.
- Spark therapy: Small sparks applied to diseased areas.
- Leyden jar shocks: Stronger pulses delivered through stored electricity.
The goal of these treatments was believed to be restoration of the body’s electrical balance.
Large medical facilities used electrotherapy extensively. One example cited in the book reports 8,686 patients treated electrically at the London Electrical Dispensary, with a large proportion reported as cured or relieved.
Electrotherapy remained common until the early twentieth century.
Early Biological Observations
Early electrical researchers observed that electricity affected many biological systems.
Reported effects included:
- Changes in pulse rate
- Stimulation of secretions
- Perspiration
- Muscle contractions
- Sensory effects (taste, light flashes, sounds)
Experiments showed that even very small electrical currents could affect the body.
Researchers such as Alexander von Humboldt conducted experiments demonstrating:
- Electrical stimulation of animal hearts
- Perception of electrical signals by human senses
- Electrical effects on nervous systems
Some experiments even revived temporarily stopped animal hearts.
These findings reinforced the belief that electricity played a fundamental role in biological processes.
Sensory Perception of Electricity
Experiments in the late eighteenth century showed that electricity could be perceived directly by the senses.
Researchers reported:
- Flashes of light when small currents were applied near the eyes
- Metallic tastes when currents touched the tongue
- Sounds produced by electrical stimulation of the ears
These experiments suggested that the nervous system itself operates electrically.
Biological Effects Observed
Early investigators documented a wide range of physiological reactions to electrical exposure.
Reported effects included:
Therapeutic effects:
- Pain relief
- Improved circulation
- Restoration of muscle function
- Stimulation of appetite
- Increased secretions
Adverse effects:
- Headaches
- Dizziness
- Nausea
- Fatigue
- Muscle pain
- Palpitations
- Respiratory symptoms
- Sleep disturbances
The book includes a table listing dozens of such effects recorded by eighteenth-century experimenters.
Electrical Sensitivity
A major theme introduced early in the book is individual variability in sensitivity to electricity.
Some people appeared highly sensitive to electrical exposure, experiencing strong symptoms even with weak electrical fields.
Examples described include:
- Scientists who developed tremors after electrical experiments
- Individuals unable to tolerate static electricity
- Experimenters who experienced headaches, dizziness, or neurological symptoms
Historical figures mentioned include:
- Thomas-François Dalibard
- Benjamin Wilson
- Johann Doppelmayer
These individuals reportedly developed long-lasting symptoms after repeated exposure.
The author suggests that electrical sensitivity was widely recognized in the eighteenth century, although the concept later disappeared from mainstream medicine.
Environmental Electricity
Early researchers also studied the influence of electrical fields on plants and animals.
Observations included:
- Increased evaporation from skin when exposed to electric fields
- Changes in plant growth
- Effects on insects and animals
One early experiment showed weight loss in electrified animals due to increased perspiration.
These findings suggested that electrical fields could influence biological processes even without direct contact.
Part II — Electricity in the Modern World
The second half of the book examines the expansion of electrical technologies over the past century.
Major developments discussed include:
- Telegraph systems
- Electrification of cities
- Radio broadcasting
- Radar
- Satellite communications
- Cellular networks
The book argues that each technological wave introduced stronger electromagnetic fields into the environment.
Historical Disease Patterns
The author proposes correlations between technological milestones and the appearance of certain diseases.
Examples discussed include:
- Global influenza pandemic coinciding with early electrical infrastructure
- Rising heart disease following electrification
- Increased cancer rates during the radio era
- Neurological symptoms during the microwave era
The book suggests that electromagnetic fields may affect biological processes such as:
- cellular respiration
- nervous system signaling
- blood chemistry
- immune response
Effects on Wildlife and Ecosystems
Later chapters examine reported effects on:
- bees
- birds
- trees
- insects
Examples discussed include:
- navigation disruption in birds
- colony collapse in bees
- forest decline
The book suggests that electromagnetic fields may interfere with biological signaling systems that evolved under natural electromagnetic conditions.
The Earth’s Electrical Environment
A key concept in the book is that life evolved within a stable natural electrical system that includes:
- atmospheric electricity
- lightning-generated waves
- Earth’s magnetic field
- natural resonance frequencies
Artificial electrical systems may disrupt this environment by introducing stronger and continuous electromagnetic radiation.
Final Argument
The concluding argument of the book is that modern civilization has transformed the electromagnetic environment on Earth in ways that could influence biological systems.
The author calls for renewed scientific investigation into:
- biological effects of electromagnetic fields
- environmental electrical pollution
- human electrical sensitivity
The book suggests that understanding the relationship between electricity and life may be essential for future public health and ecological stability.
Key Themes
Major ideas developed throughout the book include:
- Electricity is fundamental to biological processes.
- Early scientists observed strong biological effects from electricity.
- Electrotherapy was widely practiced for centuries.
- Electrical sensitivity varies widely between individuals.
- Modern electromagnetic technology has dramatically altered Earth’s electrical environment.

All content summarized from the uploaded book The Invisible Rainbow: A History of Electricity and Life by Arthur Firstenberg.
1. Chapter-by-Chapter Summary (17 Chapters)
Chapter 1 – Captured in a Bottle
This chapter recounts the discovery of stored electricity through the Leyden jar experiment in 1746. Scientists including Pieter van Musschenbroek and Ewald Georg von Kleist demonstrated that electricity could be stored and discharged from a glass container.
The discovery caused widespread public fascination known as “electromania.” Public demonstrations involved chains of people holding hands while electric shocks passed through them simultaneously.
Electricity quickly became a form of entertainment, social curiosity, and experimental medical treatment. Physicians and amateur practitioners began using electrical shocks to treat paralysis, nervous disorders, and other ailments.
The author emphasizes that early experimenters frequently warned about potential dangers, but those warnings were largely ignored due to the excitement surrounding the new technology.
Chapter 2 – The Deaf to Hear, and the Lame to Walk
Early electrical researchers observed numerous biological effects from small electrical currents.
Electrotherapy became widely used in the eighteenth and nineteenth centuries. Treatments included electrical baths, sparks, and small pulses applied to nerves and muscles.
Several physicians reported dramatic results in restoring hearing to individuals suffering from nerve deafness.
One notable example involved neurologist Guillaume Duchenne de Boulogne, who used mild electrical pulses applied to the ear canal to restore hearing in several patients.
Early electrical researchers also demonstrated that electricity could affect the heart, muscles, and nervous system, reinforcing the idea that electricity plays a role in biological functioning.
Chapter 3 – Electrical Sensitivity
This chapter documents early reports of individuals who reacted strongly to electrical exposure.
Some scientists who performed electrical experiments experienced:
- tremors
- neurological symptoms
- headaches
- dizziness
- long-term health effects
Benjamin Franklin himself reportedly developed recurring neurological symptoms during the years he conducted electrical experiments.
Early electricians recognized that sensitivity to electricity varied greatly between individuals.
The concept of electrical sensitivity was widely acknowledged during the eighteenth and nineteenth centuries but later disappeared from mainstream medical research.
Chapter 4 – The Road Not Taken
The author explores the early development of electrical biology and argues that scientific research once recognized the connection between electricity and living organisms.
However, as electrical engineering advanced, scientific attention shifted toward technological applications rather than biological effects.
The emerging electrical industry focused on power generation, communication, and machinery, while research into biological electrical effects declined.
The chapter suggests that this shift caused a large body of earlier biological knowledge to be ignored.
Chapter 5 – Chronic Electrical Illness
Reports accumulated during the nineteenth century describing chronic illnesses associated with electrical exposure.
Symptoms reported by physicians included:
- fatigue
- nervous disorders
- heart palpitations
- headaches
- depression
Some doctors believed these conditions were related to exposure to telegraph systems and early electrical infrastructure.
The chapter argues that chronic electrical illness was once recognized by physicians but was later dismissed.
Chapter 6 – The Behavior of Plants
Early agricultural experiments explored how electricity affected plant growth.
Farmers and scientists experimented with electrified fields and seeds.
Some experiments suggested that electrical exposure accelerated plant growth and improved crop yields.
Other experiments suggested harmful effects.
The chapter emphasizes that plants appear highly sensitive to electrical fields.
Chapter 7 – Acute Electrical Illness
Cases of acute electrical injury were reported during the early electrification era.
Symptoms observed after exposure to electrical shocks included:
- neurological problems
- paralysis
- heart disturbances
- seizures
These cases led some physicians to warn about widespread exposure to electrical currents.
However, as electricity became increasingly common, concern over these effects diminished.
Chapter 8 – Mystery on the Isle of Wight
This chapter examines unusual illnesses that occurred among telegraph workers and residents near electrical installations in the late nineteenth century.
Symptoms included:
- heart irregularities
- fatigue
- neurological symptoms
The chapter explores the possibility that exposure to electrical infrastructure contributed to these illnesses.
Chapter 9 – Earth’s Electric Envelope
The Earth possesses a natural electrical system that includes atmospheric electricity, lightning activity, and electromagnetic resonances.
Life evolved within this natural electrical environment.
The chapter describes how biological organisms interact with natural electromagnetic fields.
Artificial electrical systems introduced during the industrial era may disrupt these natural conditions.
Chapter 10 – Porphyrins and the Basis of Life
Porphyrins are essential molecules involved in biological processes such as oxygen transport and cellular respiration.
Examples include:
- hemoglobin
- chlorophyll
The chapter argues that these molecules interact with electromagnetic fields.
According to the author, this interaction may explain why electrical fields influence biological systems.
Chapter 11 – Irritable Heart
This chapter explores historical increases in heart disease following the spread of electrical infrastructure.
Early medical literature described a condition known as “irritable heart.”
Symptoms included:
- rapid heartbeat
- chest pain
- fatigue
- nervous disturbances
The chapter examines possible links between electrical exposure and cardiovascular symptoms.
Chapter 12 – The Transformation of Diabetes
The author argues that the nature of diabetes changed during the late nineteenth and early twentieth centuries.
Historically, diabetes was rare and occurred mostly in thin individuals.
In modern times it has become widespread and often associated with obesity.
The chapter suggests that environmental changes, including electrification, may have influenced metabolic diseases.
Chapter 13 – Cancer and the Starvation of Life
This chapter discusses cancer and its relationship to cellular respiration.
The author references research suggesting that electromagnetic fields may influence oxygen metabolism and cellular energy production.
The chapter proposes that disruptions in these processes could contribute to cancer development.
Chapter 14 – Suspended Animation
Experiments in electrical stimulation have shown that electricity can temporarily revive organisms or restore biological activity.
Historical experiments demonstrated that electrical pulses could restart animal hearts or revive apparently dead animals for short periods.
The chapter explores the relationship between electricity and cellular life processes.
Chapter 15 – You Mean You Can Hear Electricity?
Some individuals report perceiving electrical signals directly through sound or sensation.
Experiments in the nineteenth century demonstrated that electrical currents could stimulate the auditory nerve.

“The Five Major Technological Waves of Electromagnetic Exposure”
which the book implicitly describes as:
- Telegraph
- AC power grids
- Radio broadcasting
- Radar & microwaves
- Cellular / wireless networks
This makes the entire thesis of the book extremely clear.
This section summarizes the five major technological waves of electromagnetic exposure described throughout The Invisible Rainbow: A History of Electricity and Life.
The Five Major Waves of Artificial Electromagnetic Exposure
Overview
Modern electrical technology did not appear all at once. Instead, it developed through a series of technological waves, each introducing new forms of electromagnetic energy into the environment.
According to the historical framework discussed in The Invisible Rainbow, these waves dramatically increased human exposure to electrical and electromagnetic fields.
Each wave introduced stronger fields, greater geographic coverage, and more continuous exposure.
Wave 1 — The Telegraph Network (1830s–1860s)
Technological Development
The first global electrical infrastructure was the telegraph network.
Key milestones included:
- 1837 — Electric telegraph demonstrated by Samuel Morse
- 1844 — First long-distance telegraph line (Washington–Baltimore)
- 1858 — First transatlantic telegraph cable
- 1860s — Telegraph networks span Europe and North America
Telegraph systems operated using long metal wires carrying pulsed electrical currents across continents.
These currents traveled through:
- overhead wires
- underground cables
- ocean cables
For the first time in human history, large-scale electrical currents were continuously transmitted across the planet.
Environmental Change
The telegraph introduced a global network of electrical conductors interacting with the Earth’s atmosphere.
Electrical currents circulated across thousands of miles of wire, connecting cities and continents.
The Earth’s electrical environment began to change.
Reported Biological Effects
Historical reports from the telegraph era described new conditions among telegraph operators, including:
- headaches
- fatigue
- nervous disorders
- heart irregularities
Some physicians referred to these conditions as “telegraphers’ disease.”
Wave 2 — Electrification and Power Grids (1880s–1920s)
Technological Development
The second wave came with the development of electrical power systems.
Key milestones:
- 1882 — First central power station (New York)
- 1880s–1890s — Spread of alternating current systems
- 1900s — Electrification of cities and homes
Electrical grids introduced continuous 50–60 Hz alternating current into homes and urban infrastructure.
Power lines and electrical wiring spread rapidly through cities.
Environmental Change
Electric fields and magnetic fields became constant features of the human environment.
Homes now contained:
- wiring in walls
- electrical appliances
- lighting systems
Cities became surrounded by large power transmission networks.
Medical Observations
Around the same time, medical literature began documenting increases in:
- cardiovascular disease
- diabetes
- neurological disorders
Some physicians speculated that electrification might influence human physiology.
Wave 3 — Radio Broadcasting (1920s–1940s)
Technological Development
The third wave began with radio broadcasting.
Key milestones:
- 1901 — First transatlantic radio signal
- 1920 — First commercial radio broadcast
- 1930s — Radio transmitters installed worldwide
Radio stations produced powerful electromagnetic transmissions that traveled through the air.
Unlike telegraph signals, radio waves were broadcast continuously in all directions.
Environmental Change
Radio transmitters introduced persistent electromagnetic radiation into the atmosphere.
These signals covered:
- entire cities
- entire countries
- eventually entire continents
This was the first time large populations were continuously immersed in artificial radio frequency radiation.
Observations and Concerns
Scientists studying atmospheric electricity noted that radio transmissions altered the natural electromagnetic environment.
However, biological research into these effects remained limited.
Wave 4 — Radar and Microwave Systems (1940s–1970s)
Technological Development
During World War II, radar systems were developed for military use.
Radar used high-frequency microwave radiation to detect aircraft and ships.
After the war, microwave technology expanded into:
- aviation radar
- weather radar
- satellite communication
- microwave transmission towers
Environmental Change
Microwave radiation was far more powerful than previous radio signals.
Radar systems generated intense pulses of electromagnetic energy.
These systems created new layers of electromagnetic radiation across the planet.
Biological Research
Some military and scientific studies investigated microwave exposure effects.
Reported symptoms included:
- headaches
- fatigue
- sleep disturbances
- neurological symptoms
These findings contributed to early discussions about microwave safety.
Wave 5 — Cellular Networks and Wireless Technology (1990s–Present)
Technological Development
The fifth wave began with the rapid expansion of wireless communication.
Key milestones:
- 1990s — Mobile phone networks expand globally
- 2000s — Wi-Fi becomes common in homes and offices
- 2010s — Smartphones and wireless devices become ubiquitous
- 2020s — Expansion of dense cellular infrastructure
Wireless communication uses microwave frequencies transmitted by:
- cell towers
- phones
- routers
- satellites
- personal devices
Environmental Change
Unlike earlier technologies, wireless devices operate continuously and in close proximity to the human body.
Sources of exposure now include:
- smartphones
- laptops
- Wi-Fi routers
- Bluetooth devices
- smart appliances
The electromagnetic environment has become increasingly dense and complex.
Comparison of the Five Waves
| Wave | Technology | Approximate Period | Key Exposure Type |
|---|---|---|---|
| 1 | Telegraph | 1830s–1860s | Long-distance electrical currents |
| 2 | Power grids | 1880s–1920s | Alternating current fields |
| 3 | Radio broadcasting | 1920s–1940s | Radio frequency radiation |
| 4 | Radar and microwaves | 1940s–1970s | High-power microwave radiation |
| 5 | Cellular and wireless | 1990s–present | Continuous wireless microwave exposure |
Summary
The development of electrical technologies occurred in successive waves, each expanding the presence of artificial electromagnetic energy in the environment.
These technological transitions transformed the Earth from a primarily natural electromagnetic system into a technologically saturated environment.
Understanding how these waves developed provides historical context for modern discussions about electricity, electromagnetic fields, and biological systems.

An extremely revealing historically that very few people notice:
A timeline overlay of the major influenza pandemics against major electrification milestones (telegraph networks, radio transmitters, radar, satellites, cellular networks).
That comparison produces a very striking chronological pattern that is discussed heavily in The Invisible Rainbow.
Below is a chronological overlay timeline placing the major influenza pandemics alongside major electrification and electromagnetic technology milestones. This format makes it easier to compare historical timing of large technological deployments with major respiratory pandemics.
This is presented in a WordPress-ready format you can paste directly into an article.

Interpretation
This overlay shows that large influenza pandemics have occurred periodically throughout history. During the modern era, these events occurred during periods when major communication or electrical technologies were being deployed.
However, chronological overlap alone does not establish causation. Epidemiologists generally attribute influenza pandemics to viral mutation, zoonotic transmission, and global travel networks.
The comparison is useful primarily as a historical timeline reference when studying the evolution of both technology and disease.
A large “Global Electrification vs Pandemic Timeline (1746–2020)” poster graphic in the same cbook7 vintage travel-poster style, with:
- telegraph poles
- radio towers
- radar dishes
- satellites
- cell towers
- historical scientists
- pandemic markers
It ends up looking like a scientific propaganda poster from the 1950s, which fits the theme extremely well.
