Although France and Germany would acquire modern industrial economies after 1850, neither was in a position to do so even a few decades earlier. Only the coming of railroads would give either country the kind of national market that was so important in Britain. The same was true for science in France, but not in Germany, for reasons that had to do with the same fragmentation that kept its economy traditional. The impact of railroad construction made up for that absence in making economic transformation possible, so that organizing spheres in accord with principles derived from the activities carried on within them would come as a concomitant of industrial transformation rather than a precondition for it. Its most striking expression would be the organization of national professional organizations, dedicated to giving doctors, engineers, chemists, and academic researchers control over their own domains, and providing essential services for modern industrial societies.
