Abstract

Sommerfeld shed no tears over Clausthal. “Now Aachen is definite, and we head there with spirits revived,” Johanna wrote her mother-in-law on December 8, 1899. The departure from Clausthal was still more than 3 months in the future, but the anticipatory joy in “the improved atmosphere and the easing of numerous social conditions” made her last winter in the Harz Mountain hinterland bearable. From the perspective of this rustic mountain town, Aachen, the “Imperial City” in the Prussian Rhine Province, must have held a particular attraction. Not just for the sake of the hot springs here did Charlemagne choose this town in the foothills of the Ardennes and the Eifel as his seat of government. From the eighteenth century on, Aachen had been a desirable address for the well-to-do, who traveled there from afar to enjoy a few weeks of recuperation in this brilliant town. In the nineteenth century, the industrial revolution brought explosive population growth to Aachen. In 1815, when the town was annexed to the Kingdom of Prussia, Aachen had around 30,000 inhabitants; by century’s end, there were already more than 130,000. Around the middle of the nineteenth century, greater Aachen was part of the most intensively industrialized regions of Germany. The “Royal Rhine-Westphalian Polytechnical School at Aachen,” founded in 1870, had as its mission to furnish engineers to the growing industries and soon was itself bursting at the seams. Though situated far from Berlin at the western corner of the kingdom, Aachen was secure in its exalted status. “And our West particularly can boast that its technology has found singular recognition in the eyes of his Imperial Majesty,” Nikolaus Holz (1868–1949), Professor of Hydraulic Engineering gushed over frequent Imperial visits from Berlin.
