Mabel White Holmes
Holmes' father, E.K. White, had founded a flour mill in 1887, which was incorporated as the Chelsea Milling Company in 1901. In 1908, White sold the company to Mabel's father-in-law, Harmon Holmes. Mabel's husband, Howard Holmes, ran the company until his death in 1936, after which she became company president. Holmes was active in the business until the early 1940s.
Holmes first had the idea for a prepared baking mix in the late 1920s when she saw the poor quality of a biscuit made by the widowed father of her sons' friend. She wanted to develop a product that would save time in the kitchen and be so easy even a contemporary man could make it. Jiffy Biscuit Mix was introduced in 1930 as America's first prepared baking mix.
