A Hundred authors against Einstein

A collection of various criticisms can be found in the book "Hundert Autoren gegen Einstein" (A Hundred authors against Einstein), published in 1931. It contains very short texts from 28 authors, and excerpts from the publications of another 19 authors. The rest consists of a list that also includes people who only for some time were opposed to relativity. Besides philosophic objections (mostly based on Kantianism), also some alleged elementary failures of the theory were included, however, as some commented, those failures were due to the authors' misunderstanding of relativity. For example, Hans Reichenbach described the book as an "accumulation of naive errors", and as "unintentionally funny". Albert von Brunn interpreted the book as a backward step to the 16th and 17th century, and Einstein is reported to have said with irony, that one author alone would have been sufficient to refute him:[1]

"If I were wrong, then one would have been enough!" --Albert Einstein, commenting on the book 100 Authors Against Einstein[2]
