I’m sure almost every one of you looked at your watch or at a clock before you came to class today. Watches and clocks seem as much a part of our life as breathing or eating. And yet, did you know that watches and clocks were scarce in the United States until the 1850s? In the late 1700s, people didn’t know the exact time unless they were near a clock. Those delightful clocks in the squares of European towns were built for the public. After all, most citizens simply couldn’t afford a personal timepiece. In the 1800s in Europe and the United States, the main purpose of a watch, which by the way was attached to a gold chain, was to show others how wealthy you were. The word "wristwatch" didn’t even enter the English language until nearly 1900. By then, the rapid pace of the industrialization in the United States meant that measuring time had become essential. How could the factory worker get to work on time unless he or she knew exactly what time it was? Since efficiency was now measured by how fast the job was done, everyone was interested in time. And since industrialization made the manufacture of large quantities of goods possible, watches became fairly inexpensive. Furthermore, electric light kept factories going around the clock. "Being on time" had entered the language and life of every citizen.
