C. Leroy Ellenberger at Fernbank Museum, Atlanta, GA, Oct 2005.
Charles Leroy Ellenberger (b.1942, known as C. Leroy) is perhaps best known as a one-time advocate, but now a prolific critic of controversial writer Immanuel Velikovsky and his works on catastrophism.
Ellenberger has degrees in chemical engineering and finance and operations research (B.S., Washington Univ.; M.B.A., Univ. of Pennsylvania). He is currently a Medical Article Retrieval Specialist in St. Louis, Missouri.
Introduction to Velikovsky
He first read Worlds in Collision in August 1969 after discovering it while browsing in the B. Dalton's Bookstore in Crestwood, Missouri. In 1979, he became a contributing editor (and later Senior Editor & Executive Secretary) to the Velikovsky-inspired Kronos journal, and has contributed material to many other publications. According to Professor of Social Theory Alfred de Grazia at New York University:
- "By 1983 Ellenberger was preparing to abandon much of quantavolution and found now that the story of Velikovsky was not without its shady tones, and more important, that Arctic ice cores and bristlecone pine dating technologies were directly contradicting Holocene quantavolutions ... ; further, that Gentry's studies of the surprising 'instant' polonium halos of creation ... were probably invalid."
Henry Bauer described Ellenberger's role in the Velikovsky scene as:
- "... a confidant to Velikovsky, a frequent visitor (often with camera) from April 1978 to his death in November 1979, and a Senior Editor of the Velikovskian journal Kronos, until the evidence forced him to conclude that Velikovsky's scientific claims were baseless. Velikovsky inscribed his copy of Ramses II and His Time "To Leroy who is consumed by the sacred flame of search for truth", 20 May 1978, and gave him permission to sell "Velikovsky's right!" T-shirts. Alfred de Grazia, impetus for The Velikovsky Affair (1966), appointed him chronicler of the continuing Velikovsky controversy in 1980. Ellenberger's last contact with Velikovsky was a phone call from him two days before he died."
- ".. has tried unceasingly but to little avail to have his former colleagues acknowledge the accumulating evidence, for example, from Greenland ice cores, that Velikovsky's claimed catastrophes did not in fact occur. Ellenberger points out, too, that Velikovsky's writings have become superfluous: astronomically plausible argument and speculation about relatively recent cosmic catastrophism can now be found in the work of Victor Clube and Bill Napier (The Cosmic Serpent, 1982; The Cosmic Winter, 1990), where the testimony of myth and historical records is also taken into account."
Association with Velikovsky
Ellenberger states that:
- "I was invited aboard by Velikovsky himself when he phoned me one evening in December 1977 in Staten Island, New York, to arrange for my meeting him after Kronos had forwarded to him copies of letters I had sent to various publications and persons defending Velikovsky against Carl Sagan. At the time I would never have even attempted to directly insinuate my existence upon Velikovsky, but he was impressed enough with my "missionary" efforts (as Greenberg used to say), that he wanted to meet me. Due to Velikovsky's health concerns, this meeting did not take place until Palm Sunday 1978 and I became a constant visitor in Princeton and Pelican Island, accepting various assignments to perform on Velkikovsky's behalf. And while he volunteered to reimburse my out of pocket expenses for photocopying and postage, he never dictated what I wrote.
- "My last contact with Velikovsky, on Thursday, November 15, 1979, two days before he died, was a phone call from him to discuss my letter on escape velocity in Kronos V:1, which ended with his agreeing to read my references which explain the physics of the matter that had been mis-handled by Velikovsky, Juergens, and Ransom ever since Yale Scientific in April 1967 up until Velikovsky and Establishment Science in 1977, as Jim Oberg had earlier explained to Warner Sizemore in a letter."
Ellenberger has described himself as a confidant to Velikovsky, rather than an assistant like Jan Sammer and Richard Heinberg.
In 1984, Ellenberger noted:
- " Over the past four years I have come to appreciate that, even if Velikovsky were right, there are good physical reasons why astronomers and other scientists have opposed him so tenaciously. Unfortunately, many of these reasons, often based on information developed since Velikovsky wrote his books, have never been discussed in Velikovskian forums or have never been discussed in a fully informed manner. Examples of the former include the Worzel Ash, ice cores, and plate tectonics. Examples of the latter include tree rings, ice age dynamics, geomagnetism, and cosmic electricity.
- " Most often, spokesmen for mainstream science such as Sagan, Asimov, Gardner, and Oberg have not expressed their criticisms using valid arguments but, rather, tend to substitute polemic, ridicule, and caricature for serious discussion. The resulting performances are riddled with errors and are received by Velikovskian partisans with diminished credibility. Their fixation on Velikovsky's text to the exclusion of later researchers in Pensée and KRONOS has also been a source of frustration. As a result, focus has been shifted away from substantive criticism in depth with more cogent criticisms having gotten side-tracked."
Ellenberger's most widely read criticisms of Velikovsky were two 1985 correspondences to Nature: "Falsifying Velikovsky" vol. 316, p. 386, and "Velikovsky's evidence?" vol. 318, p. 204, and two 1987 letters to the editor in New York Times: May 15, p. 14, and August 29, p. 14. The second Times letter was rebutted by Clark Whelton in a letter published September 29. Although the Times did not print Ellenberger's point-by-point surrebuttal to Whelton's letter, it was distributed (a) privately by mail with the September 1, 1987 "Dear Friends" letter and (b) to all attendees at the August 1990 "Reconsidering Velikovsky" Conference in Toronto.
In 1994, Ellenberger was disinvited from a conference on Velikovsky because other participants said they would not attend if he participated. This incident was instigated by the same group who in 1992 had deleted the section "Magnetism, Dynamos and Neptune" from Ellenberger's invited memoir for Aeon that explained the ignorance of Velikovsky and many of his supporters concerning the role of electromagnetism in astronomy and the origin of planetary magnetic fields. Previously, he was an invited speaker at Milton Zysman's August 1990 "Reconsidering Velikovsky" Conference at University of Toronto, identified on the program as "Velikovsky's most unrelenting critic" who was interviewed for The Globe and Mail, and he was the keynote speaker at the August 1992 Canadian Society for Interdisciplinary Studies conference in Haliburton, Ontario. He is also the author of the article "Top Ten Reasons Why Velikovsky Is Wrong About Worlds in Collision" which he says:
- ".. is based on 30 years exposure to Velikovsky's ideas which includes 8 years as an insider at the Velikovsky journal Kronos (1978 - 1986), confidant to Velikovsky (4/78 - 11/79), invited "Devil's Advocate" at Aeon ('88 - '91), and 13 years as a turncoat/critic interacting with Velikovsky's defenders and/or successors at conferences, in private, and in Usenet ('94 -'96) & list-serve forums."
Of these attempts to de-program Velikovsky's supporters, Henry Bauer noted Ellenberger "has tried unceasingly but to little avail to have his former colleagues acknowledge the accumulating evidence, for example, from Greenland ice cores, that Velikovsky's claimed catastrophes did not in fact occur." His resignation from Kronos as senior editor in December 1986 was acknowledged by Martin Gardner, who previously noted Ellenberger's "vitriolic" letters defending Velikovsky. Regarding Ellenberger's defection, Skeptic editor Michael Shermer declared: "One major strike against Velikovsky is that Leroy Ellenberger, a one-time Velikovsky supporter, after stepping outside of the paradigm to examine the evidence in a clearer light, now completely rejects all tenets of the theory." Sagan biographer Keay Davidson credits Ellenberger "In my experience" as "the single richest source of information on the Velikovsky controversy." Astronomer Dennis Rawlins hails Ellenberger "the world's top anti-Velikovsky expert". NASA astronomer David Morrison, who has monitored the Velikovsky scene since 1972, has thanked Ellenberger for helping "to look at these issues from the other side and to appreciate how poorly the scientific critics communicated with the public."
At the 1990 Toronto conference, the keynote address by British astronomer Victor Clube was titled "The Dynamics of Armageddon". Clube and his colleague Bill Napier propose a Taurid complex model of energetic, episodic interaction between Earth and Comet Encke with its then-heavy debris streams all through the Holocene, as an astronomically feasible explanation for the origin of the sky-combat myths that motivated Velikovsky.
Clube and Napier's model
Ellenberger came to accept Clube and Napier's model as a scientifically valid and intellectually satisfying replacement for Velikovsky-inspired models of recent, interplanetary catastrophism. Astronomer David Morrison noted:
- "In fact, the work of Clube and Napier attracts many people who were once impressed by Velikovsky, such as Leroy Ellenberger, at one time a member of the Velikovsky inner circle and now one of the most outspoken critics of his current followers".
Since 1990, Ellenberger has actively promoted Clube and Napier's model, now named "coherent catastrophism", in articles for Skeptic, C&C Review, and Catastrophism and Ancient History, letters to editors, postcard mailing campaigns to Velikovskians, and posts to Usenet discussion groups. He has also embraced a second line of research to use in criticism of the neo-Velikovskian "Saturn Thesis" model, namely, the ancient harmonic cosmology decoded by Ernest G. McClain in which the sacred number names of the major Sumero-Babylonian gods correspond to harmonic ratios of the octave.
Many authors have sought Ellenberger's editorial assistance concerning Velikovsky, catastrophism, and related topics, or cited his work, including John White, British independent researcher Peter Warlow, professor of chemistry and science studies Henry Bauer, professor of political studies J.W. Grove, professor of physics Michael Friedlander, British ancient history scholar Peter James, radioastronomer Gerrit Verschuur, Irish palaeoecologist Mike Baillie, British biologist Trevor Palmer, physicist and astronomer Phil Plait (a.k.a. The Bad Astronomer), professor of philosophy Robert Todd Carroll, and professor of biology William Stansfield.
Donald W. Patten has commented that:
- "In court, attorneys will often pound the table harder when their cases are especially weak. Ellenberger assumes the role of advocate for uniformitarianism and he does get combative and strident. Personally in telephone conversations, however, he has been amiable, even though in print he postures as an attorney might to a jury. [..]"
- "Ellenberger portrayed Windsor's work as "fundamentally flawed," "useless," "disingenuous," and "theoretically unsound." These adjectives were used with emotional or subjective verbs. It would appear that Ellenberger, for whatever reason, is subjective and emotional. [..] Ellenberger's critique is good enough to cause concern and study, but under scrutiny it does not have much substance."
Charles Ginenthal has devoted an article to criticizing Ellenberger's behavior in The Velikovskian, "The Ellenberger And Internet Debunkers":
- ".. behind many of the present-day efforts to destroy Velikovsky and those of us who stand by his work is a former Velikovskian, C. Leroy Ellenberger, and a group of Internet debunkers. In a sense he and they represent the epitome of enraged anti-Velikovskian thought and behavior today. Many of us in the Velikovsky movement have long been familiar with his and their methods of trying to completely demolish anything and everything positive related to Velikovsky. He and they maintain that they are only acting as objective, honest critics and are only working in the best interests of science an truth with diligence employing ethical scholarship. [..]"
- "The character of these communications by Ellenberger is nothing less than obscenity, the obscene thoughts of a man out of control. These kinds of communications are not only crude, but indicate that Ellenberger is incapable of maintaining his equilibrium way Velikovskians. In fact, he has sent such missives in postcard form even when dealing with some of us at our places of employment where colleagues could see them. [..] His coarse and highly inappropriate behavior has made Ellenberger persona non grata to me and several others in the Velikovsky movement."
Kronos Editor-in-Chief Lewis M. Greenberg has written:
- "Now to Ellenberger. If nothing else, he is an "equal opportunity offender". Over the past fifteen years, both orthodoxy and heterodoxy alike, in the New World and the Old, have been equally insulted, maligned, and castigated by Ellenberger's waspish writing. A blizzard of missives -- a veritable "Post Card Winter" -- has descended on all who are perceived to be on the wrong side of Ellenberger's current beliefs. [..]
- "When Ellenberger finally resigned from Kronos [..] Ellenberger claims to have "lost confidence in the Editor-in-Chief's editorial judgment and objectivity" and that "the playing field was no longer level for" him. The playing field had not been level for quite awhile; it had been slanted in Ellenberger's favor. But, after I discovered that he was savaging would-be contributors before the fact, in private, was savaging them again in print, and was then savaging them after the fact in both private and print, this became too much. At work, at home, or at play, people were being bombarded by post and by phone."
Ellenberger has responded to these particular examples (and others).
- Regarding Donald W. Patten's criticism, Ellenberger writes that he ".. was dismayed at the nature and quality of their replies. Their many assertions were seldom supported by anything substantial, rigorous, quantitative, or valid [..] their replies do nothing to verify their model and, in fact, throw more smoke than light on the issues.."
- Regarding Charles Ginenthal's criticisms, Ellenberger has commented that ".. Ginenthal's criticisms are mostly taken out of context, especially his over-the-top reaction to a particular postcard sent to 35 people in December 1995"
- Regarding Lewis M. Greenberg's criticisms, Ellenberger comments that he was: "not permitted to reply to it in Aeon because, as I was told in June 1993 when the conclusion to my invited memoir was cancelled, my being barred as a contributor to Aeon was a condition of Greenberg's joining Aeon's staff and that ban included replying to Greenberg's criticism."

Although Gingerich selects Peter Huber's analysis of the Babylonian Venus tablets for this purpose, they simply are not decisive enough. Indeed, Rose and Vaughan's critique of Huber, to which Gingerich alludes, is stronger than he allows. "The best evidence proving Velikovsky's scenario did not happen is provided by Greenland's Dye 3 ice core. This core is continuous and datable by counting annual layers back at least 7,200 years. Velikovsky's catastrophes should have left unequivocal markers in the ice. Not only are the expected heavy dust layers absent, but volcanic acid fallout, identified with ancient eruptions in the Velikovskian time frame, is comparable in amount to that associated with single, recent eruptions. This is not what would be expected if catastrophes of the magnitude described by Velikovsky had actually happened. C.
