[Oradlist] Important anniversary

[Ruprecht, Axel]

And, you do have an umlaut. The "e" after the o is the umlaut. :)

Axel, Interestingly enough I used Otto's radiograph last Friday in a CE course to emphasize how far we had come.  Unfortunately I am not related to Walter but I'm sure he pronounced his name correctly unlike the American pronunciation of Koenig...which only my German colleague pronounces as if it still had an umlaut :)  Lisa

As Professor Ken Abramovitch (Houston) reminded me yesterday, today is the 114th anniversary of the first dental radiograph. I am using the images prepared by Ken, as it saves me having to dig it out of my own History of Radiology lecture. And no, contrary to popular opinion, I did not make the first dental radiograph. The radiographs were made by Dr. Otto Walkoff, of Braunschweig, Germany. The exposure time was 25 minutes. That's right, minutes. Walkoff later went on to become professor of radiology at Munich. I do not know if he suffered any ill effects of radiation the way so many of the pioneers did.

It is interesting that these radiographs were made 15 days after Röntgen made the discovery of the x ray public. Twenty days later Dr. Walter König (any relation Lisa?) of Frankfurt Germany made another set of radiographs on February 1. with an exposure time of 9 minutes (see below). He later became a professor at Giessen, which is where Röntgen is buried. I think that his were better, almost diagnostic.

For those of you of a later vintage, in 1995, on the hundred anniversary the discovery of the x ray, the Radiology Centennial Institute (I believe that was the proper name) created a time capsule which included lectures on various aspects of the history radiology. OM Radiology has a lecture in there. They did sell copies of the lectures. I do not know if they still have these. The place to check would be with the American College of Radiology, in Reston Virginia, if you are interested.
