Heinrich, H.W., 1886-1962

Herbert William Heinrich was an Assistant Superintendent of the Engineering and Inspection Division of Travelers Insurance Company when he published his book Industrial Accident Prevention, A Scientific Approach, in 1931. One empirical finding from his book became known as Heinrich's Law: that in a workplace, for every accident that causes a major injury, there are 29 accidents that cause minor injuries and 300 accidents that cause no injuries.
