This is a remarkable resource of imagery and will be a boon for anybody carrying out historical research – such as AHS members.
There are countless images of interest in this release, each one of which might augment an existing research project or prompt a new one. The beauty of archives such as this is the opportunity for lateral thinking. You might be researching a particular village, or writer, or building, or period. And you might find an image here that opens up new avenues of research.
The first four images I found are the result of searching for ‘clock’ or ‘clocktower’ – as you’d expect, lots of public clocks.
But let’s say I’m interested in chronometers. Unfortunately there are no search returns for that word. But then I tried searching for ‘observatory’, and found this image.
It’s from a book on the North Polar Expedition, and it’s a photograph of marine chronometers on show in a US Navy centennial exhibit in 1876. That led me to this catalogue of the objects exhibited. And on pages 79–81 there’s a remarkable and detailed description of the use of chronometers at the US Naval Observatory in the 1870s. Serendipitous discovery is a wonderful thing.
You’ll probably want to put aside an hour or two browsing these images – and a lot more time following the interesting leads they throw up! Happy hunting, and happy new year.
