When we teach innovation at the world’s largest companies and in Stanford University’s most popular courses on entrepreneurship, we often start by asking what these four innovations have in common: (1) the moving disassembly lines of Chicago slaughterhouses in the late 1800s; (2) quick-drying nitrocellulose black lacquer used in what is known as “japanning”; (3) staff profit-sharing, introduced by Procter & Gamble’s cofounder William Procter in 1887; and (4) Isaac Singer’s 19th-century network of local dealers selling sewing machines. Even the brightest corporate and startup minds rarely guess the correct answer. When revealed, however, it seems obvious: Henry Ford.
