Known for practical, inviting household books, this early 20th-century American writer published guides that helped readers serve drinks and cook with confidence. Her best-known titles reflect the everyday creativity and thrift of their era.

by Bertha E. L. (Bertha Edson Lay) Stockbridge
Bertha E. L. Stockbridge, also published as Bertha Edson Lay Stockbridge, was an American author active in the 1910s and 1920s. She is credited with books including The Liberty Cook Book (1918) and What to Drink: The Blue Book of Beverages (1920), both focused on practical home cooking and non-alcoholic refreshments.
The surviving record available online is fairly sparse, but library and public-domain catalog entries show her work reaching a wide readership and remaining accessible today. Her beverage book, in particular, stands out as a lively collection of recipes and serving ideas for social occasions.
Some sources list her birth year differently, but the dates provided here follow the information you supplied: 1871–1950. I wasn't able to confirm enough reliable biographical detail beyond her published works to say more with confidence.
