Ferdinand Reich (19 February 1799 &ndash; 27 April 1882) was a German chemist who co-discovered indium in 1863 with Hieronymous Theodor Richter.
Reich was born in Bernburg, Anhalt-Bernburg and died in Freiberg.  He was color blind, or could only see in whites and blacks, and that is why Theodor Richter became his science partner.  Richter would examine the colors produced in reactions that they studied.
Reich and Richter ended up isolating the indium, creating a small supply, although it was later found in more regions.  They isolated the indium at the Freiberg University of Mining and Technology in Germany.
In 1803, Laplace and Gauss both derived that, if a heavy object is dropped from a height  at latitude , and the earth rotates from west to east with angular velocity , then the object would be deflected to the east by a distance of . In 1831, Reich set out to test this prediction by actually dropping objects in a mine pit (Drei-Brüder-Schacht, with latitude 50° 53′ 12.5″  N) 158.5 m deep, in Freiberg, Saxony, for 106 times. The average deflection is 2.84 cm to the east and 0.44 cm to the south. The eastward deflection is almost exactly equal to the theoretical value of 2.75 cm, but the southward deflection remains unexplained to this day. The experiment is published in
