Most Influential Scientists of All Time
a Yourlist ranking · the crowd decides the order
Vote for the scientists whose ideas most transformed humanity's understanding of the universe. Rank them by the reach and lasting power of their discoveries.
What counts: Ranking reflects breadth and depth of scientific influence, longevity of impact, and how much modern science and technology rests on their work. Birth/death years and field are approximate for historical figures; ratings are subjective community estimates.
