In 1900, a series of experiments by Paul Uhlenhuth led to a serum that reacted to the presence of human blood, but not to the blood of animals. The crime investigator would dissolve blood evidence in salt water, and then add the solution to the special serum. Human blood darkened the serum via the precipitation of a protein. The 1904 slaying of nine-year-old Lucie Berlin was the first murder case solved by the amazing new blood detection method.
