The study of alcohol as an academic exercise, however, can be traced to the late 1700s when J.J. Plenc proposed the chemical
identification of poisons
In the United States, Indiana University's Prof. Rolla N. Harger conducted the first-ever "short course" on chemical
tests for intoxication in 1937. Dr. Harger also introduced the Drunkometer, the first stable instrument for testing breath
alcohol, in 1938.
In 1954, Professor Robert F. Borkenstein of Indiana University invented the Breathalyzer, the first practical instrument
for testing breath alcohol. Whereas the The Drunkometer required re-calibration when it was moved from place to place, the Breathalyzer was highly portable.
