The medical X-ray, like many inventions, is the result of different people working simultaneously on the same idea. Weeks after German scientist Wilhelm Roentgen announced in late 1895 the discovery of a “mysterious light” emitted from Crookes tubes, scientists and engineers from all over the world began experiments. One such person was Frank Austin, class of 1895, a physics assistant at Dartmouth and later a professor at Thayer. Using equipment he built, Austin made a number of X-ray photographs, including one of his own hand in late January of 1896. On February 3, 1896, at Austin’s suggestion, Hanover physician Dr. Gilman Frost and his brother, physics professor Edwin Frost, took a diagnostic X-ray of local schoolboy Eddie McCarthy’s broken wrist.
Until recently, Dartmouth had undisputed bragging rites for the first medical X-ray. Then Yale claimed that one of its physicists made an X-ray image on January 27, 1896.
“If Yale’s physicist, Arthur Wright, preempted the Dartmouth group,” writes Dr. Peter Spiegel ’58 DMS’59, a Dartmouth radiologist who has done extensive research on the history of the X-ray, “it remains unreported and unsubstantiated, at least in the scientific literature. The Dartmouth group went one step further. The taking of the first clinical X-ray in America was captured by photographer Henry H. Barrett and so remains the first scientific experiment recorded by photographic means.”

Editor’s Note: The photograph to which Dr. Spiegel refers actually was taken by H.H. Langill with the assistance of Henry H. Barrett.

I have an hours long Powerpoint presentation on the history of x-ray, CT, and MRI history and technologic advances. This photo is PHENOMENAL! I’m amazed these men were thinking ahead… RECORDING such an historic event.
Thank you so much for posting and sharing these images!
Henry H. Barrett was my Grandfather and left me many of his photographs. Some of these are xrays on glass plates.
It is great to find this information published on the web. My Grandmother took care of Dr. Frost’s wife after he passed away. Their house is across the street from the Dartmouth gym and is now owned by the college.
