Gender: Male Religion: Jewish Race or Ethnicity: White Occupation: Physicist Nationality: Germany Executive summary: Cathode rays German physicist Eugen Goldstein studied under Hermann von Helmholtz, and coined the term "cathode rays", for the negatively-charged electrons discovered by Johann Hittorf, emitted when electric current is forced through a vacuum tube. He discovered anode rays (also called canal rays), the positively-charged particles formed when electrons are removed from the gas particles in a cathode-ray tube. He showed that cathode rays can cast shadows, then demonstrated how such rays are emitted, perpendicular to the cathode surface, and can be manipulated with magnetic fields. Goldstein's work suggested the presence of the proton -- a positively charged particle, later discovered by Ernest Rutherford.
