Arthur D. Hall III papers
Arthur D. Hall (1924-2006) was a systems engineer who spent the first part of his career with Bell Telephone Laboratories and later taught at the University of Pennsylvania and conducted an independent consulting business. In the latter capacity he developed a patented automated agricultural production system that the called "Autofarm," but was unable to make the leap from invention to true innovation. It was an early, but failed attempt at "green" farming. The Arthur D. Hall III papers represent a portion of his total archive that survived at the time of his death and was removed from his home office in Fredericksburg, Virginia. The main focus of the papers is Hall's work to develop Autofarm and his unsuccessful attempts to secure funding and market the concept to paying customers. There are smaller amounts of material dealing with his career at Bell Labs and his writing and publishing efforts.
