Late 1940s: Willard F. Libby develops radiocarbon dating. His 1949 papers are followed by the University of Chicago Press monograph Radiocarbon Dating in 1952. Carbon-14 decay dates organic material back roughly 50,000–60,000 years. Conventional radiocarbon ages can differ from calendar ages by around 1,000–1,500 years, in either direction; tree-ring data help calibrate them to calendar years before AD 1950 🏺🔬
Willard Libby Devises Radiocarbon Dating; Monograph Published in 1952
Key facts
- Libby's radiocarbon-dating papers appeared in 1949; the University of Chicago Press monograph Radiocarbon Dating was published in 1952.
- Radiocarbon dating uses carbon-14 decay to estimate the age of organic material and is practical to roughly 50,000–60,000 years.
- Conventional radiocarbon ages can differ from calendar ages by around 1,000–1,500 years, with the direction of the difference varying by period.
- Dendrochronology provides a major calibration record; cal BP denotes calendar years before AD 1950.
