Hundred-year-old cookbooks often included advertisements at the back of the book, which helped defray the costs of printing the book. Here’s a 1917 cookbook advertisement for oleomargarine. (Yes, they had margarine back than – though they called it by a longer name.). It appeared in The Housewife’s Cook Book (1917) by Lilla Frich.
The book was self-published by Ms. Frich. (Is Ms. the right title to use when writing about a woman who wrote more than 50 years before the term was term was commonly used?) She was the Supervisor of Domestic Science for the Minneapolis Public Schools.
Even though the book’s title refers to “housewife’s,” I think that the book was written for use in high school domestic science (home ec) classes. I guess the presumption was that students needed to be taught skills in school so that they were prepared for their future careers as homemakers.
