Latest revision as of 09:25, 17 November 2024

In this Dutch name, the surname is De Vries, not Vries.
In this article, we use Dutch capitalization for the tussenvoegsels in Dutch family names. The first letter in De Vries is capitalized unless it is preceded by a name, initial or title of nobility.

Hessel de Vries (November 15, 1916 – December 23, 1959), 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 sciences. The 1960 Nobel Prize in Chemistry was awarded to Willard Libby for his radiocarbon-dating method, however De Vries was not a contender, since the prize is not awarded posthumously and Hessel de Vries died in Groningen in 1959 by suicide after murdering an analyst, Anneke Hoogeveen.[1] He has been called "the unsung hero of radiocarbon dating" by Eric Willis, the first director of the radiocarbon-dating laboratory at the University of Cambridge.[2] His other major area of research included studies of human color vision and hearing.[3][4] De Vries became a member of the Royal Netherlands Academy of Arts and Sciences in 1956.[5]

Vision science

[edit]

In 1943 De Vries discovered a law of scotopic vision that was further investigated by Albert Rose and is known as the De Vries–Rose law. He investigated the effect of temperature on vision by requiring subjects to sit in hot baths.[1]

De Vries effect

[edit]

In 1958, de Vries showed that baffling anomalies in the carbon-14 dates, observed by Willard Frank Libby for Egyptological samples, were in fact systematic anomalies on a global scale, represented in the carbon-14 dates of tree rings. This phenomenon has been called the "De Vries effect".[6] The correspondence with tree rings, which can be counted (one ring for each year), led to a recalibration of radiocarbon dating that was a large improvement in the accuracy.

Murder and suicide

[edit]

De Vries became obsessed with his assistant, Anneke Hoogeveen, and left his wife and children in the hope of being with her. In December 1959 De Vries stabbed her to death with a chisel at her parents' home, then killed himself using cyanide.[1][7][8][9]
