Special Relativity
Einstein's first paper on relativity was published in 1905. Length Contraction was first written about by Fitzgerald in 1889.

Read this description of length contraction. It will give you an idea of its significance.

Basically, the length of a moving object in its direction of motion is shorter than it would be if it were at rest.
There's a difference between the theory Einstein published and the length contraction by George Fitzgerald. With Fitzgerald's theory there's an ether and with Einstein’s theory there is no ether. The link I gave describes both Fitzgerald’s theory and Einstein’s theory. They have the same description even though there’s an ether in Fitzgerald’s theory and not in Einstein’s.
Earlier than 1905, Poincare pointed out that you can apply Occam's razor to Fitzgerald's length contraction theory and as a result you will have the same theory but without the ether. That length contraction theory is the same as the length contraction that Einstein wrote about later on.
Time Dilation theory was first developed by some guy named Larmor in 1897 and another guy named Poincare.
This will explain the theory:

Basically, a moving clock runs slower than a clock at rest.
Applying Occam’s razor to Larmor’s theory you get the same theory that appeared in Einstein’s later 1905 paper.
The Lorentz Transformations were first derived by Joseph Larmor. Here’s the Lorentz Transformation

Again you can apply Occam's razor and you have the same Lorentz transformations that Einstein would later write about.
Some people give Einstein credit for the Special Theory of relativity because of his 'derivation' of the Lorentz Transformations, but his derivation wasn’t any good.
E=m (c^2)
Einstein was not the first to publish this theory.

General relativity
The Einstein field equations are the theory of general relativity and Einstein wasn't the first to get them published. David Hilbert was the first
