Quick Answer
Ernest Rutherford and Bertram Boltwood were early pioneers of radiometric dating in the early 1900s. Their methods used radioactive decay to estimate geological ages.
The Full Story
At the start of the 20th century, Ernest Rutherford and Bertram Boltwood showed that radioactive decay could be used as a natural clock. Boltwood applied the idea to uranium-bearing minerals and produced some of the first age estimates for rocks. Their work opened the door to radiometric dating, which became essential for determining the ages of Earth materials and geologic events. Radiometric methods later refined the age of Earth to billions of years.
