Hello I am trying to find information about what inspired people to become scientists. I know that there are some big events that are often mentioned such as the apollo missions. But I cannot find any information from a confirmed reliable source that states this. ie. all I have now is anecdotal information. Also, I've heard that many scientists were inspired by popularizers like Carl Sagan. Again, the only info I have about this is anecdotal - So, is there any reliable source that has perhaps surveyed scientists and can perhaps statistically support the claim that popularizers like Sagan inspired people to become scientists?
