The Shipping Container: Malcolm McLean and Globalization

Before the 1950s, loading a single ship took days and a small army of longshoremen hauling crates, barrels, and bales one at a time. Then a trucking entrepreneur named Malcolm McLean, who knew almost nothing about ships, looked at the chaos at the docks and asked a deceptively simple question. In 1956 his idea sailed out of Newark in a metal box, and within decades shipping costs had collapsed and factories on one continent were quietly stocking shelves on another.

For founders and operators, this is the rare case where the most boring-sounding decision reshaped an entire global economy. It sharpens how you think about the unglamorous handoffs between teams, partners, and systems in your own business: the places where work piles up, gets lost, or gets repacked for no reason. McLean's bet identifies a kind of leverage hiding in plain sight, and the case forces you to find your own version before you read what he actually did with it.
