The Box — How Shipping Was Reinvented in 1956
Containerisation, Malcolm McLean, and the standardised steel box that reshaped the world economy
On the morning of April 26, 1956, a converted World War II tanker called the Ideal X sailed from Port Newark, New Jersey, carrying fifty-eight metal boxes welded to its deck. The boxes were thirty-five feet long, the same width as the eighteen-wheeler trailers that had delivered them to the dock. The cargo inside was unremarkable — household goods, machine parts, the usual freight of mid-century coastal trade.
What was different was the time it took to load. A traditional break-bulk freighter — the kind that had carried world commerce for the previous two centuries — would have spent a week tied to the dock while longshoremen carried barrels, sacks, and crates one piece at a time into the hold. The Ideal X was loaded in less than eight hours.
The freight cost per ton on her maiden voyage worked out to roughly sixteen cents.
