And the solitary genius who first understood transmission lines (and many other implications of

Maxwell's equations) was Oliver Heaviside. He worked out that you could add regular load inductors

to telegraph wires to allow them to carry information much faster, invented the coaxial cable,

invented iron-cored copper wire for increasing distributed inductance, invented a practical

duplex telegraph circuit for long distance (IIRC), reformulated Maxwell's 20-or-so equations

into the modern 4 vector calculus equations (Hertz also did this independently I think), codiscovered

the Poynting vector...

He is much underrated in my opinion:
