Consider the case of Einstein, who gave qm such a start with his photoelectric paper, and was in his turn a plain drag on qm when he so aggressively opposed the theory of qm as it developed. Physicists are polite about this point as they hate to admit their tin god Einstein could be so definitely wrong; they excuse him this way and that, but under pressure they have to admit that once again the person who opened up the field did not understand what he had done, and is best ignored at a later date!
