Plate I

A museum display of a short vertical section of transatlantic telephone cable with its layers of coating progressively stripped back from top to bottom, exposing a central copper conductor, then successive layers of insulation, steel armour wires, and an outer wrapped jacket labelled TRANSATLANTIC TELEPHONE, DEEP SEA TYPE, SUBMARINE CABLES LIMITED.
A section of TAT-1 cable, its layers stripped back to show the engineering underneath: the same autumn a DuPont chemist was patenting a plastic built for exactly this kind of unforgiving precision, if at a much smaller scale.

The Post-War Boom

1956

Polyacetal (POM)

Revolutionizing Precision

At four o'clock on the afternoon of 25 September 1956, the Postmaster General in London lifted a telephone in Lancaster House and spoke to the chairman of AT&T in New York. The words travelled through TAT-1, the first telephone cable ever laid across the Atlantic seabed, and the connection held. The cable itself was unremarkable copper and gutta-percha-descended insulation, but the achievement that mattered was buried three miles down in its 102 signal repeaters: valves engineered so precisely, and so far beyond any hope of repair once submerged, that they were built to run without failure for twenty years. They ran for twenty-two, and never once failed.
