We asked “What’s this Gadget?” about a set of twenty-five uncaptioned photographs from the Harris & Ewing Collection, and you definitely put on your thinking caps – or maybe your psychographs – which we learned the smiling woman below is “wearing”!
The thought-provoking image above was just one of the photographs added to our Mystery Photos album in the Library of Congress Flickr account, with the most recent batch all focused on some kind of contraption.
The amount of information located for the photo below by our diligent Flickr watchers was astounding, and all backed up with citations, photographs and other sources. We learned about both the man and the scientific gadget depicted, and the photo went from being wholly unidentified to having this detailed caption: [Charles Greeley Abbot, astrophysicist and Secretary of the Smithsonian, with his device: a silver-disc pyrheliometer which measures direct beam solar irradiance].
