Ferdinand Reich [1799-1882]
Reich, who was born at Bernburg in Germany, studied at the University of Gottingen and taught at the Freiberg Mining Academy. In 1863 he obtained a yellow precipitate from some local zinc ores. Convinced that it contained a new element he asked his assistant Hieronymus Richter to examine it spectroscopically (he himself was colour blind). Richter found a new line in the dark blue region that confirmed Reich's original conviction; the new element was named ' indium ' after the bright indigo line characteristic of its spectrum.
