Alchemists
They were around from 500-1600 AD. They were the first people to perform hands-on experimentation. They were part philosopher, mystic, magician, and chemist. They believed that elements could be changed into others and they attempted to change base metals into more valuable ones but in the process they discovered many new elements and facts on existing elements. They also believed they could find a substance that would give them eternal life. -
