C. Leroy Ellenberger

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. In 1979, he became a contributing editor (and later Senior Editor) to the Velikovsky-inspired Kronos journal, and has contributed material to many other publications. . 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."

In 1994, Ellenberger was disinvited from a conference on Velikovsky because other participants said they would not attend if he participated. 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"

Ellenberger has degrees in chemical engineering and finance & operations research (B.S., Washington Univ.; M.B.A., Univ. of Pennsylvania). He is currently a Medical Article Retrieval Specialist in St. Louis, Missouri,
