Of the people named or implied to be named, the last, the son John Annan, died in 1947:
This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag. Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag. |
Or, if we presume the photographer is anonymous, it's still published before 1929, the year that things automatically go out of copyright in the United States, so that's fine, and it's also still out of copyright in the UK under:

- ↑ File:Baron-Kelvin-William-Thomson-compass-1902.jpg identifies the photographer as specifically James Craig Annan, but I can't find any source for that attribution.
Additionally, the National Galleries of Scotland offer a CC-by-NC license, for which they suggest Wikipedia as a suitable use. Nice of them, and I'll take advantage of their offer, but to upload, have to claim {{PD-Art}} or {{PD-scan}}
