I'm glad I searched before posting something similar. General Relatively is one of the greatest individual efforts in the history of science. I do think there is something noble about the self-isolation and dedication to his work that Einstein is reported to have had. While the list demonstrates somewhat anti-social behavior, espessially by today's standards, its unfortunate that the context is missing from the article.
Whether it is an individual effort or joint effort that Einstein took all the credits fro later, it is still not 100% sure. See the page[1] about Mileva Marić.
It wouldn't be the first time in the history of science that one man was recognized for something just because he was louder in self promotion (see Tesla vs Edison).
I don't claim that Mileva Marić is of Tesla caliber, but treating woman that is as educated as her husband, and who also participated and contributed highly in his early work as a mere home service says a lot about person doing it.
I agree that his Special Relativity work was probably worked on with some contribution of Marić, but I think his later work was more individual. Others may deserve credit for some of it though http://en.wikipedia.org/wiki/Relativity_priority_dispute
History has a way of attributing contributions to the foremost scientist of the era. For example, "Newtonian" physics implies and is often taught to have all been first discribed by Newton, when in reality it was a joint effort of him, Galileo, Kepler, Descarte, Hooke, Leibniz, and others.
