Johannes Stark was a German physicist born in 1875 in Bavaria, Germany. He made significant contributions in the fields of electric currents in gases, spectroscopic analysis, and chemical valency. His greatest accomplishment was publishing over 300 scientific papers. Stark discovered the Doppler effect in canal rays and the splitting of spectral lines in electric fields, for which he received the 1919 Nobel Prize in Physics. He held positions at several universities during his career and received other awards including the Baumgartner Prize and Vahlbruch Prize for his scientific work. Stark founded the Jahrbuch der Radioaktivität und Elektronik scientific journal and edited it from 1904 to 1913.
