Just to clarify things. Einsten was taught physics at several universities in Germany.
As far as I remember he did not get his Ph.D. until after he published the special theory of relativity in 1905 (he also published his work on the photoelectric effect the same year), I think the topic of his thesis was Brownian motion. He got his Ph.D in 1905 or 1906. The point is that even though it is true that he was not an established scientist when he published his theories he had studied physics for many years and he definitly had a lot of formal training (the math needed in his work on Brownian motion is quite complicated and definitly not something an amateur would understand).
There are more recent examples of people that have done ground-breaking work withour beeing established in the scientific community, for example Josephson (Nobel prize in 1971 or 1972 for work he did as a graduate student) or this years Nobel price winner in Chemistray Tanaka (works as an engineer at a private company in Japan). However, all of them have had some , and in most cases a lot of, formal training.
