Collection Creator Biography:

Ellenberger, C. Leroy

Charles Leroy Ellenberger (born 1942) was a one-time advocate and now critic of controversial psychiatrist, psychoanalyst, and author, Immanuel Velikovsky and his works on catastrophism. Ellenberger served as senior editor of the Velikovskian journal Kronos; but around 1984, he began publishing criticisms, having concluded that Velikovsky's scientific claims were baseless.
