    Biography / Administrative History

    Dr. Weast and his wife Elsie are credited with developing and patenting low-calorie and low-sugar diet foods in the early 1950s while working for Tillie Lewis Foods. They pioneered canned diabetic foods, low salt vegetables, low cholesterol eggs, low cholesterol pancake mix, low calorie carbonated beverages, and new processes for canning.
    Dr. Weast was born in 1913 in Modesto, California, grew up in Big Oak Flat near Yosemite National Park and attended high school in Sonora. He met Elsie Orr while attending Modesto Junior College in 1933 and they were married seven years later while pursuing graduate degrees in nutrition and agricultural chemistry at the University of California at Berkeley.
    In 1946, Weast joined Flotill Products Inc., which changed its name to Tillie Lewis Foods in 1961, and was purchased by Ogden Corporation in 1965. Tillie Lewis built her first tomato cannery in Stockton in 1935 and eventually controlled a 100 million dollar a year business. Lewis had a special lab built in the attic of the Weast's home in Manteca so Elsie could develop diet foods and still take care of their two daughters. Dr. Weast was sent by Lewis to Australia and Paraguay to help those operations in the southern hemisphere. He had served as plant manager, Vice President Technical Director for Lewis's plants in Stockton, but spent most of his tenure in the laboratory developing new foods. Weast retired in 1978.
    Dr. Weast briefly assisted with the College of Pacific food science program in the late 1940s.
    The Weast family vacations frequently took them to the historic Spanish missions from the tip of Baja California in Mexico to the San Francisco Solano Mission in Sonoma, California. Dr. Weast documented the missions through his extensive slide photography collection.

    Scope and Content of Collection

    The collection consists of Weast biographical material and a significant assortment of photos and slides that document Tillie Lewis Foods and Weast's interest in Spanish Missions. The biographical materials shed light on Weast's career and include some of his published work and a bibliography of his articles. Many of the diet plans that the Weasts developed are also available in this collection. The photography documents the work and conditions at the canning factories in the Valley and in Australia and Paraguay. The balance of the collection contains dozens of slides taken in the 1950s and 1960s of the Spanish Missions of Baja California, Mexico and California. These mission images provide a snapshot of building conditions and interpretation that may be useful for historic preservation.
