UV light is used to sterilize things. I had a cabinet in my classroom for safety glasses. It had timer with a UV light to sterilize glasses between classes.
Have to remember that all medical procedures are "practices". They practice one thing until they discover it is not really a good thing to do, then they practice something else. They used to "bleed" people also to let the "bad blood" out, among other crazy things.

This study model in plaster in a scale of 1/5 inch = 1 foot was constructed by Emile Garet (wearing hat in photo), an architect sculptor, for the Architect of the Capitol as part of a 1904 report for the extension of the East Front of the U.S. Capitol. It was constructed so that the extension could be removed to compare the Capitol as it then existed with the proposed changes of 1904. The delicate carvings and attention to detail made this model a popular attraction at international expositions in the early 20th century. It was displayed in the crypt of the Capitol from 1938 to 1976, when it was moved to this location. The extension of the East Front was ultimately constructed between 1958 and 1962.

re: #1093, the dockworkers and haul of fish.
Yes, imagine the smell on a warm sunny day something best to avoid.
But as with certain other black and white photos, exemplary technique on full display. Stone white to pitch black and every grey between, pale compared to spectacular depth of field. Prior to digitization for online, probably ~10% sharper yet.
#1095 has some interesting black and white contrast right down to the asbestos pipe insulation.
