I cannot imagine living in 1916 with any amount of money. I think of the heavy wool clothing, the lack of air conditioning, the prevalence flies due to the ubiquity of horse manure, the absence of window screens, the home refrigerator, rubber-soled shoes, peanut butter, the list goes on.
Peanut butter has been around since the late 19th Century:
