I just watched Albert Einstein: Greatest Mind of the Twentieth Century | Full Documentary | Biography" on YouTube...

I learned a couple new things I didn't know about him... He basically had an open relationship with his last wife before she died. He didn't know and never saw his first born child. They gave it up for adoption, because he didn't want it to interfere with his life and projects. That bothered me. The child didn't know... but it would be an awful feeling to know as a child, you didn't Trump your parent's careers.

The end of the documentary explained that he went to the doctor with chest pains.. The doctor said it was a relive easy procedure but Einstein declined, saying he wanted to die naturally and not have any life saving procedures done.
