Daniel_Barringer_(geologist)--Eugene_Shoemaker

Daniel Barringer (May 25, 1860 – November 30, 1929) was a geologist best known as the first person to prove the existence of an impact crater on the Earth, Meteor Crater in Arizona. The site has been renamed the Barringer Crater in his honor, which is the preferred name used in the scientific community. A small lunar crater on the far side of the Moon is also named after him.
