Bruno J. Strasser and Thomas Schlich's "The Mask"

Bruno J. Strasser is a historian, a full professor at the University of Geneva, and an affiliate of History of Medicine at Yale University. Thomas Schlich is the James McGill Professor in the History of Medicine at McGill University, and a former practicing physician.

They applied the "Page 99 Test" to their new book, The Mask: A History of Breathing Bad Air, with the following results:
Page 99 reflects quite well the tone and content of the book!

This chapter—“Fog, Fumes, and Fashion”—explores the use of masks against urban pollution in the 19th and 20th centuries. In the late 19th century, such masks became popular in large British cities like London, Manchester, and Leeds. People sought to avoid breathing the mix of coal fumes, industrial vapors, and cold, damp air that made up the winter “fogs.”

Page 99 examines how French physicians reacted to what they thought was the British craze for masks. They were unanimous in condemning the practice. They found it “ridiculous”—and the fact that it was British didn’t help. Some feared that one day “entire families might be seen masked in the streets.” Masks, they thought, were useless, a symbol of the excesses of the hygienic movement. One physician even warned that if masks ever became mandatory, it would mean “the end of the kiss.”

The chapter then shifts to the Great Smog of London in 1952, during which over ten thousand people died from air pollution. Once again, many people—especially the police—wore masks. Churchill’s health minister, a chain smoker himself, didn’t believe masks could protect citizens from the smog. But facing mounting public anger, he gave in and recommended their use to save his political career.

Page 99, like the rest of the book, shows that masks have always been controversial. Masks were often seen as a convenient “technological fix” for complex medical and environmental challenges, but not everybody agreed on this kind of quick fix. In the book, we tell these stories to help us think about what kinds of environments we all want to live and breathe in.
