Philipp Lenard - "Deutsche Physik"

"Deutsche Physik"

Lenard is remembered today as a strong German nationalist who despised English physics, which he considered as having stolen its ideas from Germany. He joined the National Socialist Party before it became politically necessary or popular to do so. During the Nazi regime, he was the outspoken proponent of the idea that Germany should rely on "Deutsche Physik" and ignore what he considered the fallacious and deliberately misleading ideas of "Jewish physics", by which he meant chiefly the theories of Albert Einstein, including "the Jewish fraud" of relativity (see also Criticism of relativity theory). An advisor to Adolf Hitler, Lenard became Chief of Aryan physics under the Nazis.

Some measure of Lenard's views on certain scientists may be deduced through examination of Lenard's book, 'Great Men in science, a History of scientific progress', first published in 1933. The book was translated into English by Dr H Stafford Hatfield with an introduction by the famous scientist Dr E.N. Da C Andrade of University College London and was widely read in schools and universities after the Second World War. The individual scientists selected for inclusion by Lenard do not include Einstein or Curie, and Andrade noted that 'A strong individuality like that of the writer of this book is bound to assert strongly individual judgements'. The publisher included what now appears to be an equally remarkable note on page xix of the 1954 English edition: "While Professor Lenard's studies of the men of science who preceded him showed not only profound knowledge but also admirable balance, when it came to men of his own time he was apt to let his own strong views on contemporary matters sway his judgement. In his lifetime he would not consent to certain modifications that were proposed in the last study of the series".

Lenard retired from Heidelberg University as professor of theoretical physics in 1931. He achieved emeritus status there, but he was expelled from his post by Allied occupation forces in 1945 when he was 83. He died in 1947 in Messelhausen.
