RE: Who was E. Frost (1896)?

["Frame, Paul" <FRAMEP@ORAU.GOV>]

Ellsworth:

A minor addition to the previous informative replies. He was a physics
professor, true, but his field was astronomy.

Your citation was right on the mark. He made the first clinical (diagnostic)
x-ray in the US. In fact I believe it was the first in North America. It was
not the first x-ray in the US (the first was non-medical), or even the first
clinical use of x-rays (x-rays might have been used in the US for therapy
prior to Frost's first clinical diagnostic x-ray).
