Claiming Einstein was a fraud is just a statement of fact.
Here is a list of quotes on the subject from a few notables;
In 1912 the Nobel prize winner (physics) Johannes Stark accused Einstein of plagiarism.
Einstein did not deny the charge, but replied;
"J. Stark has written a comment on a recently published paper of mine for the purpose of defending his intellectual property. I will not go into the question of priority that he has raised, because this would hardly interest anyone, all the more so because the law of photochemical equivalence is a self-evident consequence of the quantum hypothesis."
Professor Reuterdahl accused Einstein of plagiarizing his work, as well as the work of others.
"No unprejudiced person can deny that, in the absence of direct and incontrovertible proofs establishing his innocence, Einstein must, in view of the circumstantial evidence previously presented, stand convicted before the world as a plagiarist."
Einstein Charged with Plagiarism, New York American, (11 April 1921)
A. Reuterdahl, "The Origin of Einsteinism", The New York Times, (12 August 1923)
Professor Westin charges Einstein with plagiarism:
Westin protested to the Directorate of the Nobel Foundation against the reward of Einstein, thus:
"From these facts the conclusion seems inevitable that Einstein cannot be regarded as a scientist of real note. He is not an honest investigator."
Reported in the New York Times, (12 April 1923).
Professor See charges Einstein with plagiarism:
"Professor See Attacks German Scientist...", The New York Times, (13 April 1923).
"Einstein a trickster?", The San Francisco Journal, (27 May 1923).
Nobel prize winner (physics) P. Lenard, E. Gehrcke, Paul Weyland, and other scientists accused Einstein of plagiarism.
"In fact, one begins to doubt the justice of these claims and to wonder if the charges (of plagiarism made against Einstein) made by a fast growing group of German scientists who, like E. Gehrcke, P. Lenard, and Paul Weyland, hold that Einstein is both a plagiarist and a sophist, are not, after all, true."
J. T. Blankart, "Relativity or Interdependence", Catholic World, Volume 112, (February, 1921)
The Nobel prize winner (physics) and friend of Einstein, Max Born, had this to say;
"Many of you may have looked up his paper 'Zur Elektrodynamik bewegter Körper' in Annalen der Physik, vol. 17, p. 811, 1905, and you will have noticed some peculiarities. The striking point is that it contains not a single reference to previous literature. It gives you the impression of quite a new venture. But that is, of course, as I have tried to explain, not true."
Max Born, "Physics and Relativity", Physics in my Generation.
Professor Nordmann implicitly charges Einstein with plagiarism:
"All this was maintained by Poincaré and others long before the time of Einstein, and one does injustice to truth in ascribing the discovery to him."
Charles Nordmann, Einstein et l'universe (1921).
If Einstein was not a fraud, these scientists would not have called Einstein a fraud.
