The subject of the book is a biography of the theoretical physicist
Arnold Sommerfeld (1868-1951). Although Sommerfeld is famous as a
quantum theorist for the elaboration of the semi-classical atomic theory
(Bohr-Sommerfeld model, Sommerfeld's fine-structure constant), his role
in the history of modern physics is not confined to atoms and quanta.
Sommerfeld left his mark in the history of mathematics, fluid mechanics,
a number of physical subdisciplines and, in particular, as founder of a
most productive "school" (Peter Debye, Wolfgang Pauli, Werner
Heisenberg, Linus Pauling and Hans Bethe were his pupils, to name only
the Nobel laureates among them). This biography is to a large extent
based on primary source material (correspondence, diaries, unpublished
manuscripts). It should be of particular interest to students who are
keen to know more about the historical roots of modern science.
Sommerfeld lived through turbulent times of German history (Wilhelmian
Empire, Weimar Republic, Nazi period). His life, therefore, illustrates
how science and scientists perform in changing social environments. From
this perspective, the biography should also attract readers with a
general interest in the history of science and technology.
