I think so, but I haven’t confirmed that yet. My inference is based on the timing of the permit application.
The reference to this comes from the 1904 article. Although I’ve been able to find the accident that caused Magonigal to break his leg, I haven’t yet found any record of the treatment he subsequently received.
The only record is indirect – his sale of a device to Hartford Hospital in November 1896. So far, I haven’t found a patent application for this device – the earliest patent application I’ve found is for a coin-operated x-ray vending machine, from September 1896, but there's no record he manufactured this vending machine. Presumably, the device he sold to Hartford Hospital wasn’t coin-operated, so I assume there’s a patent application out there waiting to be found.
Green’s obituary in the Hartford Courant stated that Green had conducted experiments in x-ray photography with Robb and Wolff, but that’s the only reference to them working together that I’ve found. There are records that Trinity students later took field trips to Green & Bauer’s factory, so there was some connection at some point, but right now, I can’t even figure out how a physicist and a bacteriologist connected to conduct x-ray demonstrations in the first place.
