James Robertson helped established the association that is in what modern-day town?
James Robertson (explorer) James Robertson (June 28, 1742 – September 1, 1814) was an American explorer, soldier and Indian agent, and one of the founding fathers of the State of Tennessee. An early companion of explorer Daniel Boone, Robertson helped establish the Watauga Association in the early 1770s, and helped defend Fort Watauga from an attack by the Cherokees in 1776. In 1779, he cofounded what is now Nashville, and was instrumental in the settlement of Middle Tennessee. He served as a brigadier general in the Southwest Territory militia in the early 1790s.
P. L. Robertson Peter Lymburner Robertson (December 10, 1879 – September 28, 1951) was a Canadian inventor, industrialist, salesman, and philanthropist who popularized the square-socket drive for screws, often called the Robertson drive. Although a square-socket drive had been conceived decades before (having been patented in 1875 by one Allan Cummings of New York City, ), it had never been developed into a commercial success, because the design was difficult to manufacture, and Robertson's efficient manufacturing technique using cold forming for the screw's head is what made the idea a commercial success. He produced his screws (patented in Canada in 1909) in his Milton, Ontario factory starting in 1908. The brand has been sold over the years, and the manufacturing for the present corporation (Robertson Inc.) is done in Jiaxing, Zhejiang, China; but the Milton, Ontario, building was still a head office for a long time before moving to nearby Burlington, Ontario.
