"Hitherto aviation has been almost monopolized by that much-overpraised
and much-overtrusted person, 'the practical man.' It is much in need
of the services of the theorist--the engineer with his mathematical
calculations of how a flying machine ought to be built and of how the
material used in its construction should be distributed to give the
greatest possible amount of strength and efficiency."
--From the _New York Times_, January 16, 1911.
