Louis PaschenDied 25 Feb 1947 at age 82 (born 22 Jan 1865).Louis Carl Heinrich Freidrich Paschen was a German physicist who was an outstanding experimental spectroscopist. In 1895, in a detailed study of the spectral series of helium, an element then newly discovered on earth, he showed the identical match with the spectral lines of helium as originally found in the solar spectrum by Janssen and Lockyer nearly 40 years earlier. He is remembered for the Paschen Series of spectral lines of hydrogen which he elucidated in 1908.« |
