Soule helped contribute to inventing one of the first practical typewriters at a machine shop located in Milwaukee, Wisconsin.[2] It was believed that Densmore had suggested splitting up commonly used letter combinations in order to solve a jamming problem, but called in question.[3] This concept was later refined by Sholes and became known as the QWERTY key layout.
