Henry Green applied for improvements to an x-ray tube.
Neat little tidbit
Green received this patent, No. 958,488, on May 17, 1910.
Put into context
As with the earlier patent on an x-ray tube that I found, Green didn’t assign this patent to Green & Bauer, and the application doesn’t refer to John Bauer. Of course, by this point, John Bauer had died, so his exclusion here is perhaps less remarkable.
