Quick Answer

Claire Patterson is the scientist who established Earth’s age at about 4.55 billion years. He did it in 1956 using lead-isotope measurements.

The Full Story

American geochemist Clair Cameron Patterson analyzed meteorites and carefully measured uranium-lead ratios to determine Earth’s age. In 1956 he published an estimate of about 4.55 billion years, which remains the accepted age to within a small margin. His work also helped reveal how much lead pollution had spread in the environment. Patterson’s research changed both geochronology and environmental science.
