Minze Stuiver (October 25, 1929 – December 26, 2020) was a geochemist who was at the forefront of geoscience research from the 1960s until his retirement in 1998. He helped transform
radiocarbon dating Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was dev ...
from a simple tool for archaeology and geology to a precise technique with applications in solar physics, oceanography, geochemistry, and carbon dynamics. Minze Stuiver's research encompassed the use of radiocarbon (14C) to understand solar cycles and radiocarbon production, ocean circulation, lake carbon dynamics and archaeology as well as the use of stable isotopes to document past climate changes.

, where he studied physics, mathematics and astronomy, focusing on nuclear physics. After graduation he joined the biophysics group led by the pre-eminent researcher
Hessel de Vries Hessel de Vries (November 15, 1916 in Annen – December 23, 1959 in Groningen), was a Dutch physicist and professor at the University of Groningen who furthered the detection methods and applications of radiocarbon dating to a variety of scie ...
and received a Ph.D. in Biophysics in 1958 with a thesis on the Biophysics of the Sense of Smell. Shortly thereafter he began working in the rapidly developing field of radiocarbon dating with de Vries, who found variations in the concentration of radiocarbon in the atmosphere which challenged the assumptions of the radiocarbon dating method. In 1959, together with his wife, Anneke, Minze went to Yale University for a one-year fellowship position but was called back to Groningen to take over as director of the radiocarbon facility when De Vries died. However Minze chose to remain in the United States at the Geochrometric Laboratory at

'' from 1977 to 1988 and broadened the scope of the publication to include articles about scientific knowledge derived from radiocarbon measurements. By then the terminology for various ways to calculate and present radiocarbon data was becoming rather confusing. Together with Henry Polach, he formulated the equations and conventions for reporting radiocarbon data that is still widely used. His work investigating atmospheric 14C changes gave rise to a greater understanding of the changes in solar activity over time and potential links to climate change as well as the extent of fossil fuel input. In the mid-1980s he led the development of the first high-precision radiocarbon calibration curve extending back nearly 10,000 years ago based on 14C measurements of tree-rings with known calendar ages from

portion of the current international radiocarbon calibration curve which is used by archaeologists and geoscientists around the world. He also oversaw the development of the CALIB computer software to automate the calibration process. In the 1990s, in addition to continued work on radiocarbon calibration and solar variability, he began work on oxygen isotopes from Greenland ice cores together with Pieter Grootes. Their sub-annual resolution stable isotopes measurements provided confirmation of the rapid nature of major climatic changes at the end of the last glaciation. Stuiver died on December 26, 2020, at the age of 91.
