|The National Cash Register Sales and Repair Building at 1011 Olive Street in the Independent City of St. Louis is eligible for listing in the National Register of Historic Places at a local level of significance under Criterion A for commerce. The building is the only remaining address that possesses a strong association with the National Cash Register Company (NCR) in St. Louis. NCR created the first mass-produced cash register and introduced it to the world as a necessity of modem business in the decades surrounding the tum of the 19th century. During the period of significance (and beyond) NCR was the globally dominant manufacturer, innovator, distributor and vendor of cash registers. In addition, its business practices proved to be highly influential among major American companies in the 20th century. In the early 20th century, St. Louis was arguably the most important American hub of NCR's operations outside of its home in Dayton, Ohio. The city was the headquarters ofNCR's Southern Sales District, the home of its only branch freight depot and distribution center in the United States, and also the home of a sales and repair center for the local market (the fourth largest metropolitan market in the country at the time). Unfortunately, the building that housed the depot and distribution center has been tom down, and the Southern District Manager simply rented space in large office buildings with, in some cases, hundreds of other tenants (thus preventing strong association of the buildings with NCR). The nominated building, NCR's St. Louis sales and repair office, however does have a strong association with the company. It is locally significant because it served as NCR's show room, the hub of its St. Louis sales force and as the repair center where all ofthe NCR machines in the area were brought for service. At the time of construction and throughout the period of significance (1913-1933), NCR was by far the dominant cash register company in St. Louis and worldwide. The nominated building recalls the important relationship that once existed between St. Louis and NCR. The .building also possesses a strong association with the widespread adoption of the cash register as a necessity of modem business in the early 20th century.
