Free exchange: The humble hero | The Economist: Containerisation changed everything. It was the brainchild of Malcom McLean, an American trucking magnate. He reckoned that big savings could be had by packing goods in uniform containers that could easily be moved between lorry and ship. When he tallied the costs from the inaugural journey of his first prototype container ship in 1956, he found that they came in at just $0.16 per tonne to load—compared with $5.83 per tonne for loose cargo on a standard ship. Containerisation quickly conquered the world: between 1966 and 1983 the share of countries with container ports rose from about 1% to nearly 90%, coinciding with a take-off in global trade (see chart).
