The first moving assembly line at Henry Ford's Model T factory in Highland Park went into operation on Oct. 7, 1913, with 140 assemblers installing parts on chassis dragged across the floor with a winch and rope along a 150-foot line.

In early January 1914, 104 years ago, the rope was replaced with an endless chain, and Ford launched the $5 work day, revolutionizing automotive production.

Ford was able to take the 3,000 parts of a Model T and divide its the production into 84 steps performed by groups of workers along the line.

With the assembly line, Ford could make a Model T every 24 seconds, selling more than 15 million worldwide by 1927 - then half of all automobiles sold.

Here's a look back in photographs at the early days of Ford's assembly line, through wartime production, all the way to modern factory operations, with workers donning exoskeleton vests.
