Containers, 20th century greatest invention?

What could be more random then talking about containers? Not much i guess...Today we don't give much relevance to them, but some say they were one of the greatest inventions of the 20th century. For centuries people all over the world couldn't deal with the losses, breaks, and deviations in international transactions between continents. Only in 1937, an american Malcom Mc Lean, at the age of 20 and owner of a small truck business, as he watched the slow cotton cargo had the idea of store them and transport them in steel boxes that could be shipped.
With time Mc Lean improved his labor methods and his company Sea-Land, today Maersk-Sealand (I bet you have seen some containers from them out there). World War 2 delayed the expansion of this invention, and only in 1966 the first shipment arrived Europe (Rotterdam) already the biggest harbor in the world. The ship "SS Fairland" used his own crane to unload the cargo since there were none at the harbor. Today there are billions containers, very important in our economy, it really helped global finances.
