Newton was the creator of a new paradigm. As part of the old he was an alchemist. As part of the new he was a scientist. Eintein was just a bead in a necklace.
Yes, I agree.
Einstein thought Newton was pretty good too.
Much of what Einstein worked on was being discussed by many physicists of the day. I give Einstein full credit for making the leap concerning light, time, and space but there were many people discussing and debating these ideas.
Newton, on the other hand, was working on ideas in secret. He wasn't collaborating with other scientists and debating "what ifs"; he came up with revolutionary ideas, as far as we know, completely on his own.
I think the difference in perception between the two is that Einsteins ideas have a "cool" factor. Warped space-time, gravity "waves", "packets" of light... weird and wild stuff.
