C. F. (Charles Ford) Langworthy

Working in the late 19th and early 20th centuries, Charles Ford Langworthy was an American chemist closely associated with the U.S. Department of Agriculture's nutrition research. Library of Congress records link him to studies on human nutrition in the United States, and the National Agricultural Library preserves a collection of his papers focused on food and nutrition.

Langworthy wrote and co-wrote a large number of government publications on familiar foods and diet, including works on fruit, potatoes, fish, cheese, mutton, eggs, and the digestibility of carbohydrates. His publications show a steady interest in explaining how food works in the body and how people could make informed choices about everyday eating.

Remembered today through his papers and his many USDA bulletins, he helped shape an early public conversation about nutrition in America. His work sits at the meeting point of chemistry, agriculture, and home economics, making technical research useful for households as well as specialists.
