Catering to the experts: food marketing and health professionals in the early 20th century

This paper aims to examine the marketing strategies designed by three innovative early 1900s food companies. It traces the coordination of these businesses’ research funding, advertising, direct mail and promotional tactics to show how they intersected and impacted consumers and health professionals in the period when scientists were first able to quantify the relationship between good health and food. The paper analyzes internal company documents, advertisements and marketing materials from Knox Gelatine, Borden and Sunkist.

Research for this paper benefited from the author’s unlimited access to the private documents of the Knox Gelatine Company and its executives. These documents were analyzed chronologically and thematically. They chronicled the company’s attempts to influence the medical world and the ways it cultivated home economists. The paper also used publicly available digitized documents from Sunkist and Borden. The paper would benefit from further detailed analysis of these documents to parse Knox’s targeting by race and ethnicity.

In the 1920s, Knox, Borden and Sunkist developed a marketing strategy which leveraged a new class of experts – the hundreds of thousands of medical professionals, home economists, teachers and government agents who advised American women. By distributing specific laboratory research on the nutritional benefits of their products to this emerging class of health professionals and the consumers who trusted them, these companies developed relationships with opinion leaders designed specifically to influence product sales.

This research benefited from access to the private documents of Knox Gelatine Company which divulge the company’s attempts to influence the medical world and cultivate home economists. The paper would benefit from further analysis of these documents to parse the company’s targeting by race and ethnicity as well as a deeper comparison to companies that tried to work with health professionals unsuccessfully and companies that adopted this tactic in the household products or tobacco area. Opportunities also exist to do a fuller analysis of variations in food marketing by rural versus urban as well as race.

By reconstructing the sequencing and content of these three companies’ 1920s marketing strategies, this research uncovers a form of early 20th century food marketing directed at health and science professionals which has been neglected in advertising histories.
