Hans Baruch (September 16, 1925 -- June 6, 2013) was an American physiologist/inventor, noted mainly for his contributions to scientific apparatus and instruments in the field of automated clinical chemistry. His Robot Chemist "was the first commercially available discrete analyzer, and probably the first to produce results with a digital print-out." Automatic discrete analysis instrumentation revolutionized the field of clinical chemistry, and, eventually, the practice of medicine, as well.
