What is an assembly line and who invented it?

An assembly line is when people specialize in making one part in order to combine all of the parts to make something. Henry Ford created the first assembly line.

Ford's assembly line starts rolling. On December 1, 1913, Henry Ford installs the first moving assembly line for the mass production of an entire automobile. His innovation reduced the time it took to build a car from more than 12 hours to two hours and 30 minutes.
