"The Thing"

Thomas Clegg (1836-1939) and his English-born father, John, built "The Thing", the first recorded self-propelled vehicle in Michigan (and perhaps in the country) in 1884-85. The Thing, driven by a single cylinder steam engine with a tubular boiler carried in the rear, seated four. The vehicle was built in the John Clegg & Son machine shop here in Memphis. It ran about 500 miles before Clegg dismantled it and sole the engine to a creamery. The shop was razed in 1936, just a short time before Henry Ford offered to buy is for a Greenfield Village.

Note: Greenfield Village is in Dearborn, Michigan and has a collection of historical buildings from the auto industry and inventions, mostly relating to Ford himself and Thomas Edison. Good place to visit. Need two days, one for the Village and one for the museum. Food is expensive, pack for a picnic.
