¿How did Einstein derived that E=mC2?. ¿ Can I find an english translation of his original paper?.

You can simply take this integral and you'll get $$E = mc^2$$

$$\int^c_0{P dv} ;$$

where $$P = mv\gamma$$

and $$\gamma = \frac{1}{\sqrt{1 - (\frac{v}{c})^2}}$$

$$\int^c_0 {\frac{mv}{\sqrt{1 - (\frac{v}{c})^2}} dv = mc^2$$
