Gregor Wentzel
German physicist (1898–1978)

Gregor Wentzel (17 February 1898 – 12 August 1978) was a German physicist known for development of quantum mechanics. Wentzel, Hendrik Kramers, and Léon Brillouin developed the Wentzel–Kramers–Brillouin approximation in 1926. In his early years, he contributed to X-ray spectroscopy, but then broadened out to make contributions to quantum mechanics, quantum electrodynamics, superconductivity and meson theory.
Biography
Early life and family
Gregor Wentzel was born in Düsseldorf, Germany, as the first of four children of Joseph and Anna Wentzel. He married Anna Lauretta Wielich and his only child, Donat Wentzel, was born in 1934. The family moved to the United States in 1948 until he and Anny returned to Ascona, Switzerland in 1970.
Education and academia
Wentzel began his university education in mathematics and physics in 1916, at the University of Freiburg. During 1917 and 1918, he served in the armed forces during World War I. He then resumed his education at the University of Freiburg until 1919, when he went to the University of Greifswald. In 1920, he went to the Ludwig-Maximilians-Universität München (LMU) to study under Arnold Sommerfeld. Wentzel was awarded his doctorate in 1921 and completed his Habilitation in 1922.

Why this record matters
“Gregor Wentzel” is worth following because a concise public description often conceals a longer documentary argument. Here, Gregor, Wentzel and German provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q91669. VIAF identifies the subject as 110384237. The Library of Congress control number is n87112946. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1898, 1978, 1926 and 1934.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
