It's from histories such as this one that I have finally come to
the conclusion that really original discoveries are rarely attributed
to the right people.  I have quite a list of similar incidents, but
I won't bore you Vorts with all of them.

This particular historical error originates from typical French
arrogance.  The great Charles de Coulomb had "proven" mathematically
that electricity and magnetism could not affect one another.  This
suppressed any notion that they might for some time, and any results
to the contrary were ignored.  Remember that Oersted's rediscovery of
this principle occured after Coulomb was dead.

Even the brilliant Ampère seems to have been diverted from discovering
the reverse effect by Coulomb's reputation, though he had coils
of wire and magnets right there on his work bench.  Instead, the credit
went to Faraday, although apparently William Henry made the discovery
slightly before Faraday, but did not publish it.

For a short period during that time you could actually be arrested in
France for publishing anything suggesting electromagnetic induction, I
suppose to protect Coulomb's reputation.  Similarly, when Davy discovered
chlorine, you could be arrested in France for publishing anything claiming
that chlorine is an element, as this contradicted Lavoisier.

On the other hand, maybe the whole thing could be attributed to the fact
that Italian scientists just can't get no respect.  Rhigi constructed
the "Van de Graaff" generator a couple of hundred years before Van de Graaff.
Olinto de Pretto published E=mc^2 a year or two before Einstein and so on.

But really, I think that humans just can't accept the truth until they
are ready.
