  • 1898

    Sheldon Laboratory Systems was founded by a teacher in 1898. A century later, we’re still in the classroom. Our founder, E.H. Sheldon, began his career as a woodworking teacher and was always looking for ways to improve the learning experience for his students. That passion led him to invent a rapid-acting vise, which was quickly followed by benches and eventually a line of laboratory furniture and furnishings for the school market.

  • 1900 – 1910

    Sheldon begins building benches to accompany his vises when manual training and domestic science are added to the curriculum of many schools.

    Initial production is handled by a Chicago woodworking shop, but the high-quality product soon results in more orders than the supplier can produce. Sheldon sets up his own factory in a Chicago loft.

    E.H. Sheldon’s brothers Henry and Thomas join the business.

  • 1911

    The company moved to Muskegon, Michigan in response to an offer of larger manufacturing facilities.

  • 1977

    The MISSCO Corporation acquires the E. H. Sheldon Equipment Co. and moves its 80-year-old operation to its present location in Crystal Springs, Mississippi.

  • Today
