Einstein is a pretty obvious pick. The other two are DEI selections (not to take anything away from their accomplishments, they just aren't two of the three most influential scientists).

I'd include Darwin on a most influential list. Evolution by natural selection is one of the most important ideas in the sciences (not just biology).

My third pick is going to be Archimedes, who advanced our understanding of mechanics tremendously. There are a bunch of worthy contenders for this slot, but so much was built off of Archimedes' work that I give him the edge.
