7 giug 1937 anni - Walter Specht

Descrizione:

In 1937, at the University Institute for Legal Medicine and Scientific Criminalistics in Jena, Germany, Walter Specht introduced the use of luminol as a presumptive test for blood at crime scenes. This is forensically important, because perpetrators often wash away visible signs of blood at the scene, in an effort to remove all possible evidence of the crime.
