Philipp Lenard Philipp Eduard Anton von Lenard , in Hungarian Fülöp Lénárd (born in Bratislava on June 7 May 20 in Messelhausen ) was a physicist and the winner of the Nobel Prize for Physics in for his research on cathode rays and the discovery of many of their properties. Missing image Lenard.jpg Lenard studied under the illustrious Bunsen and Helmholtz , and obtained his doctoral degree in 1886 at the University of Heidelberg . After posts at Aachen, Bonn, Aix-la-Chappell, Breslau, Heidelberg (1896-1898), and Kiel (1898-1907), he returned finally to the University of Heidelberg in 1907 as the head of the Philipp Lenard Institute. Lenard is best remembered as an "experimentalist of genius" whose major contributions were in the study of cathode rays. Prior to his work, cathode rays were produced in Crookes ' tubes (an early form of the now ubiquitous cathode ray tube , or CRT), which are partially evacuated glass tubes that have metallic electrodes in them, across which a high voltage can be placed. The rays were difficult to study because they were inside sealed glass tubes, difficult to access, and because the rays were in the presence of air molecules (fully evacuated tubes didn't produce rays). He overcame these problems by devising a method of making small metallic windows in the glass that were thick enough to be able to withstand the pressure differences, but thin enough to allow passage of the rays. Having made a window for the rays, he could pass them out into the laboratory, or, alternatively, into another chamber that was completely evacuated. He was able to conveniently detect the rays and measure their intensity by means of paper sheets coated with phosphorescent materials.

Emergence of Modern Science The Discovery of the Electron V.B.Kamble A s early as about 1830, electrical discharges in gases were intriguing a number of experimental physicists in Europe. In 1881, at the Cavendish Laboratory at the University of Cambridge, J.J.Thomson began experimenting with gaseous discharges, and continued to do so for the next 50 years. When Thomson started his research, cathode rays had already been known for about 50 years, but their nature was controversial. As Thomson later wrote in the paper reporting his discovery of the electron, "The most diverse opinions are held as to these rays; according to the almost unanimous opinion of German physicists they are due to some process in the ether to which. no phenomenon hitherto observed is analogous; another view of these rays is that, so far from being wholly ethereal, they are in fact wholly material, and that they mark the paths of particles of matter charged with negative electricity."

60. A Chronology Of The Atomic View Of Nature 1899, philipp eduard anton VON lenard (Germany, 18621947), showed that photoelectricemission is due to electrons. 1899, JOSEPH JOHN THOMSON (England, http://www.3rd1000.com/chronoatoms.htm

A CHRONOLOGY OF THE ATOMIC VIEW OF NATURE c. 550 B.C. THALES of Miletus (Greece, c. 640-546 B.C.) recorded the attractive properties of rubbed amber and of lodestone. c. 450 B.C. LEUCIPPUS (Greece) proposed an atomic concept of matter. c. 400 B.C. DEMOCRITUS of Abdera (Greece, c. 460-357 B.C.) pupil of Leucippus, was the most famous of the atomists in ancient times. He taught: "The only existing things are the atoms and empty space; all else is mere opinion. " c. 335 B.C. ARISTOTLE (Greece, 384-322 B.C.) held that all matter was basically composed of the same continuous primordial stuff. c. 300 B.C. EPICURUS of Samos (Greece, c. 342-270 B.C.) founded a philosophical system based on the atomism of Democritus. c. B.C. ZENO of Cition (Greece, c. 336-264 B.C.) founded the Stoic school of philosophy which held that matter, space, etc. were continuous. c. 60 B.C. TITUS LUCRETIUS CARUS (Rome, c. 96-55 B.C.) attempted to formulate a rational explanation of natural phenomena by extending the beliefs of Democritus and Epicurus. His poem, De Rerum Natura, is the most complete record of Greek atomism extant. The atomism of antiquity was primarily a system of metaphysics. The atomic view of matter in the modern sense was barely introduced in its most elementary form by the beginning of the 19th century.
