Who do you think is the most important scientist?

there was a lot of change throughout history and not every major historical scientific figure was covered in the readings. and you may not be done with the readings yet. but of those that you have read about, who do you think is the most influential to the process of scientific thought and to the development of scientific methodology and why? answer this question in 250 words or less and respond to two other student's posts. remember, science is not just about one topic or the biology, chemistry, physics, earth, but it is about a way of thinking about a problem as we discovered in our last unit.
