[Back to the Future] "It works! I finally built something that works!!" - Doc Brown Brown was a genius who had time, money, and resources to spend all of his time inventing things. How had nothing worked until the time machine?

The impression given was that Doc Brown was a great genius it turned out, but at heart a tinkerer. He was a full blown genius. But none of his truly important ideas or theories had ever proven or worked. He did build lots of small stuff that worked no doubt, the Rube Goldberg devices in his house for example, but he likely did not even consider such things important. Time travel was his great contribution to Science, the one big idea that worked out.
