This has often reminded me of something that occurred around 1776.
I can't remember if it was before or after.
Remember how the colonies got sophisticated spinning gear?
I believe it was spinning gear.
Great Britain had a ban on the export of functional models, diagrams or
manufacturing instructions to one particular class of equipment.  This was
so that they could maintain the monopoly on cheaply made cloth, holding the
outlying colonies in line by maintaining a dependancy.
One man memorized the structure of one of these machines and then came to
the American shores, where he reproduced it workably.

I can't remember the name of the man or the machine, just that it was used
in the manufacture of cloth, the "spinning jenny" i think.  Nor can I
remember the date.
