Illustration of Halley’s Comet (Newsprint) – Herschel (1835)

General knowledge and understanding of electricity progressed at an exponential rate in the late 18th century as electricity increasingly offered new and feasible explanations for hitherto mysterious natural phenomena. Scientists across Europe and the World wrote a vast number of books and scientific articles about the nature of electricity and the history of its uses, properties, and behaviors.

Early Enthusiasm in the Science of Electricity

Turn of the 18th/19th Century

Joseph Priestley (1733-1804)
The History and Present State of Electricity with Original Experiments.

1775 A.D. – Joseph Priestley

Joseph Priestley, a British theologian, chemist, and physicist published “The History and Present State of Electricity with Original Experiments” in 1767. The third edition of this book (1775) is given particular credence by proponents of the Electric Universe. Priestley was, by most accounts, the first researcher to compare electrical scars from discharge experiments with massive structures peppering the moon’s surface. He wrote:

“JUNE the 14th. I took the spot upon smooth pieces of lead and silver. It was, in both cases, like that on the brass knob, only the central spot on the silver consisted of dots disposed with the utmost exactness, like radii from the center of a circle, each of which terminated a little short of the external circle.


Cratered Surface of The Moon – Priestley pioneered comparative research between moon craters and electric discharge scarring.

EXAMINING the spots with a microscope, both the shining dots that formed the central spot, and those which formed the external circle, appeared evidently to consist of cavities, resembling those of the moon, as they appear through a telescope, the edges projecting shadows into them, when they were held in the sun.”

1783 A.D. – Johann August Donndorff

The German physician Johann August Donndorff (1754-1837) was a public figure and diligent poly-historian who authored several scientific and technological works. He published “Science of Electricity, Theoretical and Practical Explanations” in two volumes, the first in 1783 and the second the following year.


“Das elektrische Planetensystem“ (The Electric Planetary System) by Benjamin Rackstrow (1748) – Donndorff described this experiment in vol. 2 p. 812-814 of his works.

Donndorff wrote detailed descriptions of 72 specific electric experiments in Chapter 19, volume II of his expansive work. He made notable contributions to the burgeoning field of study in Germany while providing support for other researchers through his inclusion and cross referencing of existing published material. Other notable German professionals published similar work during the same period of time in what was becoming a thriving scientific community.

1783 A.D. – Karl Gottlob Kühn

Karl Gottlob Kühn, physician and medical historian of Saxony, published his book “History of Medical and Physical Electricity and the Newest Attempts, made in this useful Science” in 1783 and 1785 (second volume.)

One of the most interesting aspects of Kühn’s work is the sheer number of natural phenomena he attributed either fully or partially to electrical activity, nearly all of which have been proven to be true. Some of these phenomena include: thunder, lightning, thunderclouds, St. Elmo’s fire, summer or “heat” lightning, the atmosphere as a whole, fireballs, aurora borealis, comet’s tails, waterspouts, hurricanes/tempests, rain, fog, hail, earthquakes (caused by subsurface lightning), volcanic eruptions (caused by electric sparks) and even connections between two volcanoes.


Aurora – Superstition still had significant influence on public perception at the time Kuehn discussed this electromagnetic phenomenon

Kühn also invested a great deal of his efforts the influence of electricity on organisms, both fauna and flora. He devoted particular focus on the human body and the use of electricity as it pertained to medicinal therapy. Kühn underlined that many researchers believed in the presence of electric atmospheres surrounding stars, planets, and comets, and assumed that electricity was also a key mechanism inside the Sun and Earth.


Georg Lichtenberg (1742-1799) – Scientist, professor, mathematician, experimenter, and poet

1791 A.D. – Georg Christoph Lichtenberg

Georg Christoph Lichtenberg was a German scientist, professor, and satirist. As a scientist, he was the first to hold a professorship explicitly dedicated to experimental physics in Germany. He found the hype surrounding electricity rather strange. The well-known pioneer of electricity was a prosaic and diligent experimenter and demanded proof for every claim. Therefore he wrote the following satirical reaction:

“…Also electric matter was named as cause of the comet‘s tail. That is the real “Scherwenzel“ [i.e. trump card] of physicists. Now all that cannot be explained in detail must have electricity as cause. Lightning and the glowing of masts were the only proven phenomena of electricity until now.”[1]


Electric Discharge Scar (Illustration) – This laboratory accident fueled Lichtenberg’s motivation to explore the phenomenon.

However, Lichtenberg himself could not resist the Zeitgeist of his era. The scientific landscape had a decidedly electric spirit. Lichtenberg speculated in Erxleben’s book “Starting Point of Natural Science” in 1791 that electricity could be — at least temporarily — involved in phenomena like “flying dragons“ (comets), shooting stars, fireballs. etc.[2]

Ernst Florens Friedrich Chladni.png

Ernst Florens Friedrich Chladni (1756-1827) – jurist, physicist, acoustician, astronomer

1794 A.D. – Ernst Chladni

Lichtenberg supported a gifted German physicist by the name of Ernst Chladni. During a discussion on their research, Chladni noticed that Lichtenberg described fireballs as if they were “electric meteors.” He called Lichtenberg’s attention to the fact that such a description was unproven and flawed. However, Lichtenberg shone light on the fact that the scientific community would not know how to conclusively describe fireballs. They could even be of cosmic origin, as comets are. This statement encouraged Chladni to carry Lichtenberg’s perspective into his own research. In 1794, he published his findings about the cosmic origin of meteorites and bolides.


Meteorite FragmentAttributed to “The Fall of Comets in L’Aigle, France (1803). Became an integral piece of evidence supporting public acceptance of Chladni’s meteorite theory.

Chladni thought that cosmic matter in the form of fireballs was attracted to and accelerated toward the Earth. This rapid motion caused strong electricity and heat due to intense friction when passing through Earth’s atmosphere. This, in turn, resulted in burning and melting, expansion and even explosion of the celestial bodies. Observation and compilation of falling stones, in conjunction with in-depth scientific discussion, had to take place before Chladni’s theory of the origin of meteorites was eventually accepted.


Ursprung der Meteorite – Chladni’s works had lasting influence on later researchers and theorists

Chladni’s published works include:

– Ueber den Ursprung der von Pallas gefundenen und anderer ihr ähnlicher Eisenmassen, und über einige damit in Verbindung stehende Naturerscheinungen (1794)

– Über den kosmischen Ursprung der Meteorite und Feuerkugeln (Reedition 1971)

-Über Feuer-Meteore und über die mit denselben herabgefallenen Massen (1819)

Johann Hieronymus Schroeter.png

Johann Hieronymus Schroeter (1745-1816) – Beobachtungen des Cometen von 1799, mit weitern cometologischen Bemerkungen (1800)

1800 A.D. – Johann Hieronymus Schroeter

Johann Hieronymus Schroeter was a German jurist, high civil servant, and prominent astronomer. His observatory in Lilienthal, a village near the City of Bremen was widely known. In early 1800, his book “Observations of the Comet of 1799, with Other Cosmological Remarks” was published. He concluded that most comets are solid bodies, but did not exclude the possible existence of fluid comets. Schroeter compared the light emitted from comets with that of Zodiacal Light (diffuse glow that extended from the horizon along the zodiac) and Northern Lights (Aurora Borealis). Furthermore, he concluded that the beams or shots of light emitted from comets are evidence of an electric meteor.


Sternwarte Lilienthaler Observatory founded by Schroeter in 1782 near the city of Bremen.

He thought so-called Lichtstoff, the “matter of light,” would be attracted by comets and transformed into light in the photosphere of the comet’s core due to the attracting and repelling actions of positive and negative electricity (or a comparable force.) Schroeter underscored that famed astronomer Wilhelm Olbers had voiced a very similar idea a year earlier in an academic talk (mid-1798.) Schroeter repeated his assumptions for the Comet of 1807 and called its ray shots “galvano-electric effects.” Following the appearance of a comet in 1811, he repeated his comparative research with Northern Lights and Zodiacal Light.

The Napoleonic Wars derailed Schroeter’s research in 1813. French troops assaulted his observatory. Most of his astronomical devices and tools were destroyed, and all of his books and writings were burned. Schroeter never overcame this tragedy and died three years later.

1800 A.D. – Jean André de Luc

Geologist and meteorologist Jean André de Luc was a Swiss geologist, natural philosopher, and meteorologist. He was born in Geneva, Switzerland and worked as a merchant. In 1773, a localized economic downturn forced him to leave his hometown. He relocated to Great Britain and was appointed reader to Queen Charlotte and the noble society until the end of his life.


Selenotopographical Illustration of the Moon – Schroeter (1791)

In 1800, he published a short paper titled “Thoughts about the Nature of Comets” in Germany. He assumed that chemical decay processes on the surface of the comet produced shining, light-like fumes arising in the comet’s atmosphere. Furthermore, de Luc compared the comet’s tail with the Northern lights and electric fluids in our atmosphere. He speculated that a fluid, comparable to so-called electric fluids present around Earth, also existed on comets.

– Kritik und Anti-Kritik meiner meteorologischen Schriften (1811)

1809 A.D. -Carl Haberle

Carl Constantin Christian Haberle worked in many fields of science in both Germany and Hungary (natural history, meteorology, mineralogy, and botany to name a few.) He published meteorological yearbooks with a full-year weather forecast in 1809 and 1810. Haberle stated that the cosmos, especially the positions of planets relative to Earth, influence weather. He further postulated that our Sun has electric interactions with neighboring stars, comets, and planets as well. Solar eruptions and sunspots were thought to be results of such interactions. Additionally, Haberle explained earthquakes as results of electric interactions.

After the publication of his yearbook for 1810, he came under heavy criticism from an anonymous reviewer. In response, his following yearbook included a supplement titled “Criticism and Anti-Criticism of my Meteorological Papers.” In this supplement, he argued for the existence of an “Ätherluft” (ether) and criticized the absence of any explanation for observed energetic phenomena in Newton’s mathematical theory of the Universe. Haberle also quoted Professor Placidus Heinrich who imagined comets as being electric or magnetic. Haberle underscored that meteorology will stay patchwork without consideration of the fact that the cosmological life of the Earth is closely connected with the cosmological life of the Sun and its family of planets, satellites, and comets. In Haberle’s opinion, God created the millions of cosmic balls in the ether with the help of electrochemistry.

However, it appears Haberle abandoned this work. In 1813, he left Germany and migrated to Hungary. There he worked as Professor of botany and mineralogy. He was murdered by a mugger in Pest, Hungary in 1832.

Franz von Paula Gruithuisen .png

Franz von Paula Gruithuisen (1774-1852) – Ueber die Natur der Kometen, mit Reflexionen auf ihre Bewohnbarkeit und Schicksale; Bey Gelegenheyt des Kometen von 1811 

1811 A.D. – Franz von Paula Gruithuisen

Franz von Paula Gruithuisen worked as a doctor in Munich, Bavaria. Prior to his cosmological work, he was famous, or perhaps infamous, for his booklet “About the Existence of Sensations in the Heads and Torsos of the Beheaded” published in 1807. However, he also worked as an astronomer and wrote an important book with 370 pages about comets, called “About the Nature of Comets, with Reflections about their Habitability and Fates during the Occasion of the Comet of 1811” (1811.)Gruithuisen shared Schroeter’s and Olber’s opinion concerning the electric nature of the comet’s light, but he added that both would miss the involved electrochemistry.

Gruithuisen had no doubt that the light of comets strongly resembled Aurora Borealis and Zodiacal Light. Therefore, he explained comet light as a polar light and a “…surplus of electricity, which developed in the chemical process on the planetary body and in its lower atmosphere. Then it finds a conductor in its upper atmosphere and is attracting electricity with the opposite charge from the ether.”[3]

The Bavarian scientist compared the comet’s tail with an experiment where electricity hits the metal button of a bell in a dark chamber of rarefied air. Later he reflected:

“The causes of the electrical processes in the atmospheres of comets and the Earth’s poles are not very different but their resulting phenomena are different. Namely the comets — possessing a rather thin, wet atmosphere — discharge easily the electricity, which is produced by the comet’s chemistry. But electricity is produced in such huge amounts that this electricity is strongly promoting the oxidation process of the comet’s vapors with the oxygen of the Sun’s atmosphere and also the production of light. That is not the case on Earth.”[4]

At the end of this section in his book, Gruithuisen delivers a rather impressive summary:

The Great Comet of 1811 (Illustration) Henry Smyth , from Amédée Guillemin ‘s The Heavens

“Therefore we can assume the most diverse chemical and dynamical processes in the ethersphere of the tail. They cause electricity but in turn this electricity is stirring chemical processes. So we have a cycle of causes of a never-ending chemistry in the atmospheres of comets. Without any doubt, these chemical processes continue with decreasing strength from every heavenly body without end in the ether and thereby cause an everlasting contra motion of the finer substances.”[5]

In later publications in the 1830’s and 1840’s, Franz von Paula Gruithuisen underlined the importance of electromagnetic variations and effects and the electrochemistry on comets.

Heinrich Wilhelm Matthäus Olbers .png

Heinrich Wilhelm Matthias Olbers (1758-1840) – Über den Schweif des großen Kometen von 1811 (1812)

1812 A.D. – Wilhelm Olbers

Heinrich Wilhelm Matthias Olbers, a well-known German astronomer, shared some association with Johann Schroeter, as was previously mentioned. He developed a theory about the electric repulsion of comet tails. It was published in January 1812 in the article “About the Tail of the Great Comet of 1811” and later reprinted.

Olbers divided comets into three classes. One class was comprised of tail-less comets. These comets did not develop matter or substance that could be influenced by any repulsive force from the Sun. The second class included comets displaying a repulsive force of the Sun, but no repulsive force within the comet. The third class categorized comets that displayed a repulsive force of the Sun and a repulsive force of the comet’s core at the same time, e.g. the Comet of 1811. Finally, Olbers concluded:

“Briefly, I do not know at all, wherefrom this repulsive force is coming, or to talk more certainly, wherefrom this aspiration of the tail matter originates to go away from the Sun and the comet’s core: it is enough that the observation shows it clearly. Meanwhile, one can hardly abstain from thinking that it is something analogous to our electric attractions and repulsions. Why should not the same mighty natural force, from which we see so important effects in our always wet and conducting atmosphere, not also operate in the big universe being effective on a scale going far beyond over our petty concepts?”[6]

Adolph (Adam?) Carl August von Eschenmayer .png

A. C. A. von Eschenmayer (1768-1852) – Grundriß der Natur-Philosophie (1832)

1832 A.D. – C. A. von Eschenmayer

Carl August von Eschenmayer, a physician and philosopher, emphasized in 1832 already the appearance of comets imposes the idea of electricity on us.[7] Eschenmayer adopted Laplace’s earlier idea of comets swinging between two suns. Near one sun, he assumed, the comet becomes saturated with either a positive or negative charge. Then the comet would rush with renewed energy to the other sun, attracted by the opposite charge of the atmosphere of this sun. Again the comet would achieve a state of saturated charge in its atmosphere, be repelled and rush to the first sun again. Therefore, the comet would demonstrate the great phenomenon of released electricity in a steady circle of attraction, saturation, and repulsion. Eschenmayer stressed that comets are not only under the influence of gravity but also by the effects of electricity.


Plasma: Double Layers Surrounding Anode – SAFIRE Project

Eschenmayer also assumed that comets have both negative and positive electric charges; a negatively charged core and a positively charged tail, which brightly glowed and expanded. From this model, he developed a revolutionary idea. He concluded that there must be an “isolierende Zwischenlage” — an insulating interlayer — between the concentration of negative charge and the concentration of positive charge. He added that science does not know the nature of this layer. In fact, he had no way of knowing the term “plasma” and its implications in 1832, but he was very close to describing the so-called “plasma double layer.”

Distressingly, Eschenmayer had an inclination for the research of occultism and animal magnetism. He was therefore ignored and later merciless ridiculed in a novel (Münchhausen by Karl Immermann.) The observation of Halley’s Comet in 1835 was not without lasting consequences for the further development of electric ideas about comets.
