In October 1913, inside Albert Kahn's glass-walled 'Crystal Palace' — a four-story factory running 865 feet along the avenue — Ford engineers brought the work to the worker for the first time: the moving assembly line. The flywheel magneto, assembled in twenty minutes by one man, was broken into twenty-nine steps and put on a moving belt. Assembly time dropped to five minutes.","The consequences came at industrial speed. Model T production went from hundreds of cars a day to thousands; the price fell from $850 to $260, cheap enough for the workers who built it to buy one. In January 1914 Ford doubled the prevailing wage to five dollars a day — an announcement so shocking that ten thousand job-seekers rioted at the gates the next morning. Employment peaked at seventy thousand in 1925. Fifteen million Model Ts had been built when the last one rolled off the line in 1927.","The plant itself never stopped working — it made trim, trucks, tractors, tanks, and aircraft engines through World War II — but production moved to the Rouge and the buildings began coming down. What remains is a National Historic Landmark, the factory where mass production was born, mostly empty now on sixty acres in a city that was built inside Detroit's boundaries for the express purpose of housing it."]},{"heading":"Why this file matters","paragraphs":["Highland Park is the archive's invention-site file — the place where the twentieth century's defining industrial idea was first bolted together, and where the working-class prosperity it created was later dismantled just as fast.","A factory that changed the world keeps its emptiness — the file's suggestion being that the Crystal Palace's most productive ghost is the assembly line itself, still moving somewhere in the building where it was invented."]}],"name":"Highland Park Plant","aliases":[],"type":"SITE","type_label":"Site","cats":["LOCAL_FOLKLORE","HAUNTED_PLACE","INDUSTRIAL","HISTORIC"],"groups":["hauntings","legends"],"desc":"The 1910 plant—where the Model T line ran.","full_desc":"Highland Park Plant is a site in Highland Park, Michigan.
