This awesome book, Hygiene for the Worker was written in 1912 and can be found on this amazing Internet book archives site. (Click on that link and it's like having the book in front of you — you can turn the pages and everything!) My favorite piece of advice for the worker involves how to handle women
on their periods when they're being visited by "the curse." The following hilarious passage is from page 172. Interested? Then
The hygiene manager of a modern factory or works will take into account only modern, scientific understandings of Female Biology. As a result, retiring rooms should be made available, where employees afflicted by The Curse during working hours can immure themselves. Such rooms should be equipt with a bell or horn, so inmates can signal the hygiene manager or his deputy, so they may signal a cab or ambulance to remove her from the workplace.
Wow. Can you imagine pulling that today? "Yo, manager, I got The Curse. Call me an ambulance, will ya?" I can't wait to flip through the rest of this! (Thanks, Boing Boing!)
