Like many other successful ventures, the concept for U-Haul was generated out of need. After World War II, there existed the widespread need for do-it-yourself moving equipment that would be available on a one-way, nationwide basis. U-Haul co-founders L.S. "Sam" Shoen and his wife, Anna Mary Carty Shoen, recognized that need and acted upon it. Their visionary approach spread the cost of ownership among many users, facilitating the mobility of the populations of the U.S. and Canada. The covered wagon of the pioneers morphed into orange U-Haul trailers. In the process, an industry was born.
