The Bureau of Home Economics, later known as the Bureau of Human Nutrition and Home Economics, was a division of the US Department of Agriculture that supported homemaker activities in the early 20th century. The bureau developed recipes, collected information from the burgeoning scientific practice of nutrition, published sewing patterns for homemade clothing, produced radio content like the Aunt Sammy personality, wrote articles for newspapers and magazines, and generally contributed to the adoption of scientific practices in routine household activities. Operating between 1923 and 1962, the bureau supported homemakers through the Great Depression and World War II.

The George Louis Beer Prize is an award given by the American Historical Association for the best book in European international history from 1895 to the present written by a United States citizen or permanent resident.

Described by Jeffrey Herf, the 1998 laureate, as "the Academy Award" of book prizes for modern European historians, it is one of the most prestigious American prizes for book-length history. The Beer Prize is usually awarded to senior scholars in the profession; the American Historical Association restricts its other distinguished European history award, the Herbert Baxter Adams Prize, to young authors publishing their first substantial work.
