What is a geologist like? Well, they are all very different. Click on the links below to get to know some famous geologists. These historic people greatly advanced our understanding of the science of geology.

  • Florence Bascom, a well known mineralogist and petrologist, led the way for American women geologists at the turn of the last century.
  • Charles Darwin, a 19th century naturalist, was the first scientist to publish a comprehensive theory of evolution.
  • Stephen Jay Gould, a 20th century biologist, paleontologist and author, further expanded Darwin's theory with his own concept of punctuated equilibrium.
  • Friedrich Mohs, a mineralogist of the early 19th century, developed a way to classify minerals by their hardness.
  • Leonardo da Vinci did a little bit of everything! When he was not painting the Mona Lisa, this 15th century "Renaissance Man" found time to be a scientist discovering how sedimentary rocks and fossils are formed.
