The wrong Baden-Powell?
I find it somewhat unlikely that the unilens should be the invention of Robert Baden-Powell, and I have not found evidence for this in the provided sources. In the reference newspaper clipping from 1907 (https://nyshistoricnewspapers.org/lccn/sn92061685/1907-07-04/ed-1/seq-6/), the inventor is given as Major Baden-Powell, F.R.A.S. This does not fit Robert, since he at the time was Major-General/Lieutenant-General. By 1907 he would also have been extremely busy writing Scouting for Boys. However, the name and title fit Robert's younger brother, Baden Baden-Powell, https://en.wikipedia.org/wiki/Baden_Baden-Powell, who was a Major and a member of the Aeronautical Society. georglind (talk) 20:14, 17 June 2022 (UTC)
