But as detailed in a recent book, The Man Who Stalked Einstein, their relationship soon deteriorated. He was a strong believer in eugenics and an enthusiastic supporter of the Nazi Party as it took power in Germany, and in return the Third Reich honored him by expanding his University of Heidelberg laboratory into the Philipp Lenard Institute.
The antagonism between Philipp Lenard and Albert Einstein sheds considerable light on the power of nonscientific concerns to sway scientists. AKA Philipp Eduard Anton Lenard. Lenard was a nationalist and anti-Semite; as an active proponent of the Nazi ideology, he supported Adolf Hitler in the 1920s and was an important role model for the "Deutsche Physik" movement during the Nazi period.  In 1880, he studied physics and chemistry in Vienna and in Budapest. Philipp Eduard Anton von Lenard (Hungarian: Lénárd Fülöp Eduárd Antal; 7 June 1862 – 20 May 1947) was a Hungarian-born German physicist and the winner of the Nobel Prize for Physics in 1905 for his work on cathode rays and the discovery of many of their properties. They are human beings too, and members of the general public need to be careful to distinguish between a scientist whose arguments are based in evidence and one whose pronouncements stem from other, less reliable sources of conviction. His work showed that electrons could be induced to radiate beyond the evacuated tube where they were produced, and that this radiation could travel short distances and penetrate sheets of metallic foil. Investigations of cathode rays. Of Einstein himself, whose ideas had been accepted by many of the most prominent physicists around the world, Lenard opined, “Just because a goat is born in a stable does not make him a noble thoroughbred.”. Lenard was a genius, operating with a deep conviction that only careful experimentation could advance the understanding of the structure of the universe. As part of the elimination of Nazi street names and monuments it was renamed in September 1945 by order of the military government. Lenard’s conviction that science, “like everything else man produces,” was somehow grounded in bloodlines led him to become one of the early adherents of National Socialism. Einstein won the Nobel prize in physics in 1921 for his discovery of the law of the photoelectric effect.
He was also an active proponent of Nazi ideology. , 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. Lenard, meanwhile, was soon swept along in a wave of German nationalism that accompanied World War I. In fact, scientists frequently disagree with one another, both as individuals and as representatives of competing schools of thought. As a result of his Crookes tube investigations, he showed that the rays produced by irradiating metals in a vacuum with ultraviolet light were similar in many respects to cathode rays. Lenard Philip HackelMemphis - Lenard Philip Hackel, 79, died over the weekend at his home. Unlike many German scientists who regarded Adolf Hitler with disdain, Lenard was one of his most fervent supporters, and became the regime’s number one physics authority. This theory predicted that the plot of the cathode ray energy versus the frequency would be a straight line with a slope equal to Planck's constant, h. This was shown to be the case some years later. Lenard retired from Heidelberg University as professor of theoretical physics in 1931.

An advisor to Adolf Hitler, Lenard became Chief of Aryan physics under the Nazis.  His father, Philipp von Lenardis (1812–1896), was a wine-merchant in Pressburg. Philipp Lenard (1862-1947) was a German experimental physicist who advanced the study of X-ray tubes, the photoelectric effect and atomic theory. Such breaches prove that scientists do not always base their work strictly on rigorous experimentation, data collection and analysis, and hypothesis testing. In 1905, Lenard became a member of the Royal Swedish Academy of Sciences, and in 1907, of the Hungarian Academy of Sciences.. He became increasingly convinced of the existence of a distinctively German physics that needed to be defended against the plagiarized or frankly fabricated work emanating from other countries. German physicist Philipp Lenard studied under Robert Wilhelm Bunsen and Hermann von Helmholtz, and won the Nobel Prize in Physics in 1905 for his investigations of cathode rays (electron beams). In Heidelberg, he studied under the illustrious Robert Bunsen, interrupted by one semester in Berlin with Hermann von Helmholtz, and he obtained a doctoral degree in 1886. Suspicious of the general adulation of Einstein, Lenard became a prominent skeptic of relativity and of Einstein's theories generally; he did not, however, dispute Einstein's explanation of the photoelectric effect. Ironically, the National Socialists’ disdain for “Jewish physics” was one of the main reasons they did not develop nuclear weapons. He proposed that every atom consists of empty space and electrically neutral corpuscules called "dynamids", each consisting of an electron and an equal positive charge. Hungarian Academy of Sciences 1907 Some of these debates rage on for years. His results led him to propose (correctly) that most of the atom is composed of empty space. The photo-electric quantum theory was the work cited when Einstein was awarded the Nobel Prize in Physics in 1921.
