Edward H. Lowe

Born 10 Jul 1920; died 4 Oct 1995 at age 75.American inventor of Kitty Litter. After Navy duty (1941-45), Lowe joined his father's company in Cassopolis, Mich., selling industrial absorbents, including sawdust and an absorbent clay called Fuller's Earth. In 1947, Lowe suggested the use of the clay instead of ashes for his neighbor's cat's box to avoid sooty paw prints. It worked well and Lowe thought other cat owners would use this new cat-box filler. He filled ten brown bags with clay, wrote the name "Kitty Litter" on them and began selling it through the local pet store. By 1990, his marketing effort had grown into a clay mining and consumer product business, the largest U.S. producer of cat-box filler, now improved, 99% dust free, and sanitized against odor-causing bacteria. He held 67 US and foreign patents.
