Two brothers, Abraham and Franklin Landis, came to the area from Lancaster County. With their inventive minds they designed and then manufactured the first cylindrical grinding machine in 1883. They formed a partnership in 1889 to manufacture and market the grinder, and six machines were sold in the first year of operation. A patent was granted to Abraham B. Landis in 1890, based on the 1883 design. The partnership was succeeded by the Landis Tool Company in 1897 and is now a division of Litton Industries. A. B. Landis then turned his attention to the problems of threading bolts, and his solution to the problem was a new and unique screw cutting die head for a turning machine, with one being built in 1887. A patent was granted in 1889, but the product was not marketed until 1903 when the Landis Machine Company was organized. This company now is known as Teledyne Landis Machine.
