Karl K. Darrow

Karl Kelchner Darrow (November 26, 1891, Chicago – June 7, 1982, New York City) was an American physicist and secretary of the American Physical Society from 1941 to 1967. He received his PhD from the University of Chicago under Robert A. Millikan in 1917. Darrow spent his working career at Western Electric from 1917 and then Bell Laboratories from its founding in 1925 until his retirement in 1956. He wrote four books and over 200 technical articles, histories, and critical reviews for professional journals, many of them in the Bell System Technical Journal. Darrow was a nephew of the famed trial attorney Clarence Darrow.
In his book "Atomic Energy" (1948), which contains four lectures he had given in 1947, he points out that in reality his subject is nuclear energy, but that at the time of the bombing of Hiroshima someone wrote of it as an atomic bomb, and the misusage spread "like a chain reaction". The book includes the following passage:
Here is the climax of my lectures, and here is where you should be frightened; and
if I had an orchestral accompaniment, here is where the orchestra would have mounted 
to a tumultuous fortissimo, with the drums rolling and the trumpets blaring and the 
tuba groaning and the strings in a frenzy, and whatever else a Richard Wagner could 
contrive to cause a sense of Gotterdammerung; for, let there be no doubt of it, this is 
something that could bring on the twilight of civilization. But at this crucial juncture I have only words to serve me, and all the words are spoiled. We speak of an 
awful headache, a dreadful cold, a frightful bore, and an appalling storm; and now 
when something comes along that is really awful and dreadful and frightful and 
appalling, all these words have been devaluated and have no terror in them. I have 
to fall back on the saying, of unknown origin and dubious value, that the strongest 
emphasis is understatement. Let then this picture, with its circles and its symbols 
and its numbers, be considered an emphatic understatement of the most terrific thing
yet known to man.
