In 1856, Perkin, an English chemist, discovered the coal-tar
(anilin) dyes. The cost of this investigation, which was
carried out in an improvised, private laboratory was
negligible. Yet, in 1905, the United States imported $5,635,164
worth of these dyes from Europe, and Germany exported
$24,065,500 worth to all parts of the world.[5] To-day we read
that great industries in this country are paralyzed because
these dyes temporarily can not be imported from Germany. All of
these vast results sprang from a modest little laboratory, a
meager equipment and the genius and patience of one man.
