> "Science" of the 1900s was heavily influenced by people willing to do whatever it took to achieve fame or fortune.

Scientific research of the 1900s made incredible improvements in medicine and technology. Most of the researchers and scientists weren't trying to be famous or extraordinarily wealthy.

The people you see pursuing fame and fortune, writing books, doing podcast tours, and all of the other fame and fortune tricks are a very small minority. Yes, people in that minority have often been discovered as writing stories that sound good to readers instead of the much more boring truth. However, most people doing science and research aren't even operating in this world of selling stories, books, and narratives to the general public. Typecasting all of "science" based on the few people you see chasing fame and fortune would be a mistake
