What did Thomas Edison, Henry Ford and Albert Einstein have in common when they

Many scientists had very bad proficiency records in their school days. Famous inventor Thomas Edison, for instance, did so poorly in his first years of school that his teacher warned his parents that he’d never be a success at anything. Similarly, Henry Ford, the father of the auto-industry, had trouble in school with both reading and writing. But perhaps the best example is Albert Einstein, whose parents and teachers suspected that he was retarded because he responded to questions so slowly and in a stuttering voice. Einstein’s high school record was poor in everything but math, and he failed his college entrance exams the first time. Even out of school the man had trouble holding a job-until he announced the theory of relativity.
