Mabel White Holmes ((1890-12-01)December 1, 1890 – November 1977) was the inventor of Jiffy baking mixes, and president of the Chelsea Milling Company.
She graduated Chelsea High School in 1907 and then went on to pursue higher education at Eastern Michigan University, then known as Ypsilanti Normal College.
[5] Holmes first had the idea for a prepared, all-purpose baking mix in the late 1920s when she saw the poor quality of a biscuit made by the widowed father of her twin sons' friend.
[3][1] According to family legend she wanted to develop a product that would save time in the kitchen and be so easy "even a man" could make it.
[5] Her grandson, Howdy Holmes, a former Indianapolis 500 and CART driver, became the current CEO of the Chelsea Milling Company in 1995.
