The German Name
In the years before the First World War, Holland America Line carried not only Dutch emigrants but a substantial number of German emigrants and German businessmen. The Rotterdam-New York route was the main Atlantic artery for much of Central Europe, and HAL had cultivated the German trade carefully. Naming a ship Potsdam — after the Prussian royal city near Berlin, the seat of Hohenzollern power — was a commercial statement as much as anything else: this line serves German passengers too, and takes their world seriously.
The SS Potsdam was one of the larger ships in the early HAL fleet. She was built around the turn of the twentieth century, when the line was growing from a collection of small iron steamships into something that could reasonably call itself a major transatlantic operator. She served on the Rotterdam-New York route through the years before the war, carrying the mixed traffic of the era: emigrants going one direction, businessmen and tourists going both.
August 1914 changed the meaning of every German name on every ship. By the time the war was over, the name Potsdam on a Dutch vessel carried a weight it hadn't carried when she was launched. The world had been remade around the names people chose before they knew what those names would mean. That is the condition of all names given before history arrives. The ship had no control over what the city became.
