If you mean about his theory of relativity then no it has never been disproved

No. Attempts have been made, and some have their doubts, but he has not been disproven.

He thought he had cool hair... he didn't, it was a total mess! Just looking at a photo of him proves that. As far as the boring physics-type stuff goes, people like Steven Hawking who specialise in space-time and black holes have raised doubts about how extensive his theory of relativity is, and quantum theory does not sit very well with the predictions made by his work, but nothing has been disproven yet and may not be, since most of the doubts about his work and simply scientific speculation as far as I am aware.

He proved himself wrong many times upon discovering new information about his topics.

His general relativity equations predicted a dynamic universe originally expanding & afterwards contracting (collapsing) due to gravity. In order to prevent that & describe the model of a stationary universe Einstein added the cosmological constant in his field equations. After Hubble proved through "redshift" that the distance between galaxies is proportional to the speed with which they are moving away from each other, the universe's expansion could not doubted, causing Einstein himself to refer to the cosmological constant as the biggest blunder of his career. Despite that, recent studies indicate that a cosmological constant taking certain values does not lead to a static but to a dynamic model of the universe, since the dark energy that the constant represents causes a negative pressure which does more than counterbalance gravity (as Einstein thought), but is responsible for the universe's accelerated expansion, which is already proven to happen (though until it was, many suggested a cosmological constant equal to zero that suggested a decelerated expansion). So in a way he was both right & wrong.

Einstein never liked Quantum Mechanics (despite having contributed to its birth). He, and another copy of guys, Podolsky and Rosen, invented a thought experiment called the EPR experiment. This showed that if Quantum Mechanics was right, information could travel in a way that *appeared* to be faster than light. He thought that this showed that QM as currently formulated was wrong, and the QM guys had some rethinking to do. However, decades later scientists were able actually to carry out his "thought experiment" (and today they do so routinely) and the experiment showed the outcome, predicted by QM, that Einstein said was impossible. QM may be crazy, but it is crazy in the same was as the Universe. Einstein's Theory of Special Relativity has certainly never been disproved. It has been tested to very high levels of accuracy. If it were to turn out to be wrong (rather than a special case of something more general, as it was to Newton), it would cause chaos in science. It is deeply built in to lots of modern technology. General Relativity is widely believed to be right as far as it goes - but it is not as complete a theory as Special Relativity. People are still looking at various effects to see if they are explained by GR or require an expanded theory. Support got GR is very very strong, but does not have the kins of rock certainty that SR has.

Yep! When he predicted that due to general relativity, Americans could never elect a president with an I.Q lower than 100, he was proven wrong twice! LOL

Only by himself, that i know of. He tested his theories numorous times to make sure he could not be disproved or to eliminate any inaccuracy in his ideas. You wouldn't release such an important discovery like a cancer cure without extensive proof and testing would you?

Scientists are not right or wrong, since they don't claim truth or falsehood. Scientists are only more or less accurate in their predictions. Was Newton wrong in supposing a model of the universe consisting of tiny billiard balls? Perhaps, but Newtonian equations constitute the vast majority of physical calculation used on this planet.

has he ever been proven right

In the 1930's Einstein said 'we can understand the universe'. This was at a time he thought the universe ended with the Milky Way galaxy. He was a steady state advocate.
