I quote from Oliver Heaviside, "Electromagnetic Theory", 1893, p.15:
It was discovered by mathematical reasoning that when an electric current
is started in a wire it begins entirely upon its skin, in fact upon the outside
of its skin; and that, in consequence, suficiently rapidly impressed fluctuations
of the current keep to the skin of the wire, and do not sensibly penetrate to
its interior.
Is this true?
