A.E. Douglass

A.E. Douglass was an astronomer and scientist who developed a method called dendrochronology, which is the study of tree rings. By analyzing the patterns of growth rings in trees, he could determine their exact ages and past climate conditions. This method allowed him to create chronological timelines that helped date archaeological artifacts and understand historical climate changes. Douglass's work revolutionized how scientists study Earth's climate history and provided accurate dating techniques essential for archaeology and geology.
