(p. 121) In 1930, Joseph Rossman, who had served for decades as an examiner in the U.S. Patent Office, polled more than seven hundred patentees. producing a remarkable picture of the mind of the inventor. Some of the results were predictable; the three biggest motivators were “love of inventing,” “desire to improve.” and “financial gain,” the ranking for each of which was statistically identical. and each at least twice as important as those appearing (p. 122) down the list, such as “desire to achieve,” “prestige,” or “altruism” (and certainly not the old saw, “laziness,” which was named roughly one-thirtieth as frequently as “financial gain”). A century after Rocket, the world of technology had changed immensely: electric power, automobiles, telephones. But the motivations of individual inventors were indistinguishable from those inaugurated by the Industrial Revolution.

In the same vein, Rossman’s survey revealed that the greatest obstacle perceived by his patentee universe was not lack of knowledge, legal difficulties, lack of time, or even prejudice against the innovation under consideration. Overwhelmingly, the largest obstacle faced by early twentieth-century inventors (and, almost certainly, their ancestors in the eighteenth century) was “lack of capital.” Inventors need investors.
