Totally false. Einsteins theory of gravity flows exclusively from the 
equivalence principle. He made three predictions:

1. The correct amount of light bending around the sun (twice as large as 
the Newtonian reconing.

2. The anomalous precession of the perihelia of planets. Mercury was the 
easist to observe but it is the case for all planets. Again he got a 
better reckoning that could be had from Newton's Law of Graviation. 
Newton knew that the orbits of the planets did not close.

3. The gravitational red-shift of light. This is something that Newton 
could not have gotten.

All three follow from the equivalence principle. Einstein did not do 
simple curve fits.

Planck did that to get a fit to the black body curve. From this curve 
fit Planck got the inspiration for the quantum of radiational energy and 
the first estimate of what is now called Planck's Constant.

And this was Einstein's major work. In his "minor" works in invented the 
quantum of light to account for the photoelectric effect and in his 
paper he came up with another way of estimating Avagadro's number.

In his later career he also did researches that established the basis of 
lasers and he predicted that the universe is expanding. Unfortunately he 
got cold feet with this prediction. Had he stayed the course, he would 
have predicted what Hubble found empirically. So even Einstein's 
"errors" were fruitful
