17-year-old Helena Muffly wrote exactly 100 years ago today:
Tuesday, November 5, 1912: I must excuse myself for this day.
Her middle-aged granddaughter’s comments 100 years later:
Since Grandma didn’t write much a hundred years ago today, I’ll tell you how long it took to complete several household tasks in 1912.
Factory managers in the 1910s believed that workers should be timed doing various tasks to determine how long it took to complete each one.
There also was a movement toward the scientific management of households. Homemakers were encouraged to time how long it took to complete common tasks so that they could better plan their daily schedule.
