Court upheld the admissibility of fingerprint evidence concluding

Jennings, Thomas
Thomas Jennings was the first person to be convicted of murder in the United States 
based on fingerprint evidence.  In 1911, Jennings appealed his conviction to the 
Illinois Supreme Court, questioning the admissibility of fingerprint evidence.  The
Illinois Supreme Court upheld his conviction concluding that fingerprint evidence 
is admissible and a reliable form of identification.  Thomas Jennings was sentenced 
to death and executed on Feb. 16, 1912 for the murder of Clarence B. Hiller.

Mary Holland, Michael P. Evans, William M. Evans, and Edward Foster were the 
four fingerprint experts that testified at Jennings original trial.

Jennings, William Nicholson (1860-1946)
William Jennings is credited with being the first person in the 
United States to record his own palm prints years apart to test their 
persistency.  After hearing a lecture at the Franklin Institute in 
Philadelphia in 1887 he recorded his prints.  In 1937 he again recorded 
his prints and saw they did not change.  Jennings did not publish 
either of the recordings until 1939.  An interesting side note is that 
this was Jennings only connection to the fingerprint industry.  Jennings 
was an internationally known photographer famous for being the first 
person to photograph lightning.
