Atomic model of Eugen Goldsteinĭespite some confusion on this issue, Goldstein never actually proposed an atomic model of his own. His discoveries, however, were essential for Thomson to develop his. In his time, Goldstein’s find was highly appreciated and became one of the foundations of contemporary physics. The rays discovered by Goldstein passed through the channels of the cathode, which is why they were called kanalstrahlen , or channel rays. In 1886, the researcher discovered that perforated cathode discharge tubes also emitted light at the end of the cathode. His conclusion was that, in addition to the already known cathode rays, there were others that moved in the opposite direction, from the negatively charged cathode to the positively charged anode. At that time, he named the light emissions investigated by other scientists as Kathodenstrahlen , or cathode rays. Goldsteín had already carried out his own studies on discharge tubes in the 1870s. Later, in 1869, Johann Wilhelm Hittorf analyzed the discharge tubes of the energy rays that extend from the cathode, the negative electrode. Goldstein’s work had as a background the studies carried out by Julius Plücker in the mid-nineteenth century on the light emitted in discharge tubes and the influence that magnetic fields had on glare.

Five years later, on December 26, 1930, he died and was buried in the Hebrew Weißensee Cemetery in the city of Berlin. In addition to these scientific activities, Goldstein served as a lawyer on matters related to Jewish immigration, a community of which he was a part.Įugen Goldstein married at an advanced age, in 1925. Goldstein also collaborated with the Institute of Technical Physics. However, most of his professional career was spent at the Potsdam Observatory, Germany. There he held the position of director of the department of astrophysics from 1927. With the help of the Academy of Sciences, he conducted a large number of experiments on electric discharges in a vacuum that led to the discovery of channel ratios. His works led him to be awarded the Hughes medal in 1908. In 1888, he became a professor at the University of Berlin. The scientist worked at the Berlin observatory between 18.

Goldstein published his first scientific work in 1876, while the last was published fifty years later. Most of them were dedicated to subjects related to what would be the great interest of their professional life: electric shocks, both in a high vacuum environment and in a moderate one. Hermann von HelmholtzĪfter studying at the Gymnasium (institute) in Ratibor, in 1869 he entered the University of Breslau. Goldstein later moved to Berlin, at whose university he completed his doctorate under the supervision of the German physicist Hermann von Helmholtz. BiographyĮugen Goldstein was born on Septemin Gleiwitz (the current Polish city of Gliwice), a town then located in Prussian Upper Silesia. His family was dedicated to viticulture, which allowed them to have a very wealthy position. The results of these experiments, in addition to other discoveries made, were published in various German magazines. Finally, his articles were gathered for publication in a work called Rayos Canales, in 1830, the same year of his death. His experiments on electric discharges in a vacuum led to the discovery of channel rays. Goldstein presented his work at the Berlin Academy in 1886 and continued his research on the same subject until the early 20th century. His conclusions on the trajectory of these rays led in 1913 to the discovery of isotopes.
