Finally, we suggest that "When thinking about individual means of protection today, it is worth asking how such measures shift responsibility for health and how, by making dangerous workplaces seem safe, they might ultimately enable the expansion of such working environments."

We also show that "Throughout the entire 19th century, masks remained a technological utopia, an unfulfilled promise that people could work safely in highly toxic environments."

In this paper, we argue that "Today's medical masks have little to do with the epidemic masks of the past. Instead, they were developed in response to the Industrial Revolution as a means of protecting people from dust and other harmful substances in the workplace."

4/12 The medical masks we use today weren’t originally invented for epidemics or hospital infections — they were created to protect workers in dusty factories!

Developed massively in the 19th C, but rarely worn until the 1920s.

In 1848, railroad worker Phineas Gage survived a 13-pound iron rod blasting through his skull. He lived, but his personality was never the same. His accident would change how we understand the brain forever. 🧵/1

The hematologist Oswald H. Robertson pioneered the idea of "blood banks" in WWI by packing glass jars of citrated blood from universal donors in an ice-filled chest that he had constructed from ammunition cases. He convinced countless others to donate blood during the war.

Violet Affleck’s impassioned call at #UNGA80 for masking and clean #indoorair is the latest episode in the long —and always controversial— history of masks. To explore the earlier chapters and better understand what’s happening today, check out our book!

3/12 - During Covid-19, men refused to wear masks more often than women. Already in the 19th c., men objected to protective masks—because real men know no fear!

Fearless Napoleon touches a plague victim with his face uncovered. His frightened marshal holds a cloth to his mouth (A.-J. Gros, 1804).

Thanks!

OK, a🧵: Our new paper studies workers' political consciousness in times of class demobilization.

We show there's more to workers' politics than right-wing resentment. Listening to workers, we reconstruct their moral critiques of money, power & recognition.

2/12 - When we look at images of people with cloths over their faces during past epidemics, we think of modern filtering masks.

In fact, these pieces of cloths were perfuming devices, soaked in vinegar, when odors caused diseases!

1/12 - In our book, The Mask, we show 58 striking images.

Remember those depictions of plague doctors wearing a beaked mask? Such visual elements were common in the 17th C and were always satirical.

Here is one by F. Bertelli, from Il Carnevale Italiano…1642 (The Met, NY).
