Clock with hour hand only, Rouen, France
When I'm trying to imagine the daily lives of my ancestors, there is a regularly occurring stumbling block. For lack of a better term, I'll call it "when-itis." As I begin to write about one of the wealthy farmers in the village proudly displaying his pendulum clock to impress my great-great grandfather, I'm suddenly wary. When was the pendulum clock invented? Would such a clock have been available for purchase in the 19th century? Nagged by doubts, I have two choices. I can spend awhile checking the Internet and reference books. Or I can write that the wealthy farmer showed my great-great grandfather his new ox.
An article in "Der Blumenbaum," the quarterly magazine of the Sacramento (California) German Genealogical Society was a happy find. It gave a timeline, going back to the first century AD, of important events, including many inventions. This list will eliminate a few guesses for me. I will be able to use that pendulum clock idea after all.
