Springer, 2009 (Vol. 1), 2018 (Vol. 2). — 777 + 867 p.
The first volume presents a selection of 434 carefully annotated letters from and to the Dutch physicist and Nobel Prize winner Hendrik Antoon Lorentz (1853-1928), covering the period from 1883 until a few months before his death in February 1928. Most of these letters are of a scientific nature, with the exception of letters between Lorentz and Albert Einstein, Max Planck, Woldemar Voigt, and Wilhelm Wien during World War I, since these letters shed important light on the disruption of scientific relations during the war and on the political views of these correspondents as well as of Lorentz.
The second and final volume contains Lorentz's scientific correspondence with Dutch colleagues, including Pieter Zeeman and Paul Ehrenfest. These 294 letters cover multiple subjects, ranging from pure mathematics to magneto-optics and wave mechanics. They reveal much about their author, including Lorentz's surprisingly active involvement in experimental matters in the first decades of his career. Letters are also devoted to general relativity, Lorentz's 1908 lecture on radiation theory, and his receipt of the Nobel Prize along with Zeeman in 1902.
The letters are being reproduced in their original language (German, French and English), and a few Dutch drafts are accompanied by English translations.
A concise biography of Lorentz is also included, as well as a full bibliography of his writings.
